The Expo grounds hummed with possibility.
Fifty thousand people packed into converted Hudson River pavilion—journalists, investors, scientists, corporate representatives, civilians hungry for hope after Manhattan invasion. Tony's stage sat center, elevated platform with Iron Man suits arranged like sentinels. My booth flanked the main area—equally prominent placement recognizing Hammer Industries' evolution.
"Nervous?" Maya asked beside me.
"Terrified. Public speaking while managing seventeen percent void corruption in front of fifty thousand people. What could go wrong?"
"Everything. But you'll do fine." She adjusted presentation materials. "Neural interface demonstration is ready. Veteran volunteer is prepped. Medical scanner is calibrated. Everything's functional."
"Then let's see if the world believes Justin Hammer became legitimate innovator."
Tony's entrance was characteristically theatrical.
Iron Man suit flew overhead, fireworks exploding in red-gold patterns, music blasting from speakers positioned across the pavilion. He landed center stage, armor retracting to reveal Tony in expensive suit underneath.
"Welcome to Stark Expo!" he announced. "Where tomorrow's technology meets today's optimism. Where innovation serves humanity instead of just corporate profits. Where even defense contractors can become... mostly decent people."
The audience laughed.
"Case in point: Justin Hammer." Tony gestured toward me. "Who somehow became legitimate innovator when I wasn't looking. Proof that people can change—even the ones who really, really annoyed me for years. Ladies and gentlemen, a round of applause for character development!"
More laughter. But genuine applause followed.
I took the stage feeling surreal. Two years ago, Justin Hammer was joke. Now I was receiving applause at Stark's showcase.
"Thank you, Tony. For the backhanded compliment and the opportunity." I addressed the audience. "Hammer Industries has transformed over the past two years. From weapons manufacturer to technology innovator. From military focus to humanitarian applications. Because technology should serve humanity—not just militaries, not just profits, but actual people who need help."
I signaled Maya. The neural interface demonstration began.
Veteran volunteer—Jason Martinez, former Marine paralyzed from waist down by IED in Afghanistan—sat in specialized wheelchair at stage side. Medical display showed his spinal cord damage clearly. Neural interface headset rested on his temples.
"Jason Martinez lost mobility three years ago. Conventional medicine said he'd never walk again. We disagreed." I activated the interface. "Neural connections between brain and prosthetic legs established through direct computer linkage. His thoughts control movement."
Jason stood.
The audience gasped. He took one step. Then another. Walking smoothly despite three years of paralysis. Tears streaming down his face.
"I can feel my legs," he said into microphone Maya provided. "Not physically. But the connection—I think about walking and it happens. It's... it's incredible."
Standing ovation. Genuine, sustained, overwhelming.
I looked at Tony. He nodded approvingly.
First time in this life I've received standing ovation for something that wasn't corporate manipulation or weapons demonstration.
Three days of demonstrations followed.
Day One focused on medical technologies—neural interfaces for paralysis, cellular scanners detecting cancer at earliest stages, regenerative treatment protocols derived from Extremis 2.0 research. Each demonstration successful, drawing interest from hospitals, research institutions, and medical NGOs.
Dr. Helen Cho approached me after cellular scanner demo. "This is remarkable work. Would you be interested in collaboration? My synthetic tissue research combined with your scanning technology could revolutionize trauma medicine."
"Absolutely. Have your people contact Maya Vasquez for partnership discussion."
Day Two showcased clean energy—arc reactor alternatives using principles Tony and I had developed through shared Chitauri research, efficient solar panels utilizing alien materials science, distributed power grids enabling developing nations to bypass fossil fuel dependency.
Multiple governments requested meetings. Saudi Arabia surprisingly progressive: "Our oil won't last forever. We're investing in alternatives now before market forces us." Smart hedging against inevitable energy transition.
Day Three demonstrated emergency response systems—Prometheus armor civilian variant designed for fire rescue and earthquake response, advanced communication networks maintaining connectivity during disasters, rapid deployment shelters using materials that deployed from compact packages.
FEMA director attended personally. "This could revolutionize disaster response. How fast can you scale production?"
"Depends on funding and regulatory approval. But we're ready to begin immediately."
Between official demonstrations, I identified enhanced individuals.
AEGIS had installed subtle screening at entrance checkpoints—biometric analysis detecting elevated radiation signatures, unusual thermal patterns, enhanced bone density, and other markers of superhuman capability. Forty-seven individuals flagged across three days.
Dr. Hank Pym attended quantum physics panel, grudgingly impressed when I asked detailed questions about subatomic manipulation. "You've actually studied quantum mechanics beyond undergraduate level."
"I read extensively. Your papers on Pym Particles were fascinating—especially the sections you published before disappearing from academic community."
"Those sections contained errors I later corrected privately."
"But the theoretical framework was sound. Shrinking objects by reducing space between atoms rather than compressing matter—elegant solution to mass retention problem."
He studied me carefully. "You're not what I expected from weapons manufacturer."
"Former weapons manufacturer. I'm trying to be something better." I handed him my card. "If you ever want to discuss quantum applications for humanitarian purposes, call me. No corporate agenda. Just scientific collaboration."
He pocketed the card without commitment. But he didn't refuse it.
Dr. Bruce Banner attended radiation containment panel—nervous, carefully controlled, clearly managing anger issues through visible effort. I approached carefully.
"Dr. Banner. Your work on gamma radiation containment is impressive."
"Thank you. You're Hammer. The one who somehow became legitimate."
"That's the general narrative. Look, I know you're cautious about partnerships after your accident. But if you ever need research facilities with no military oversight and no government reporting requirements, Hammer Industries has space. No strings attached."
"Why would you offer that?"
"Because brilliant scientists deserve to research without looking over their shoulders for generals trying to weaponize their work. And because the world needs your mind focused on problems instead of just managing consequences of one experiment gone wrong."
He looked surprised. "That's... unexpectedly decent."
"I'm trying to build reputation for unexpected decency. Spreading goodwill against future need." I handed him my card. "Offer stands whenever you're ready."
The most surprising contact was Peter Parker.
Fifteen-year-old kid, Queens high school, first place in science competition Tony sponsored. Genius-level intellect evident in his chemical adhesive research. Also registering elevated biomarkers suggesting enhanced abilities he wasn't revealing.
Spider-Man. Three years early. What the hell?
"Peter Parker?" I approached him at the student exhibition area.
"Mr. Hammer! I mean, yes, that's me. Hi. Your neural interface presentation was incredible. The signal processing algorithms alone—" He stopped, clearly nervous. "Sorry, I'm rambling."
"Don't apologize for enthusiasm about technical achievement. Your adhesive research is impressive. Chemical bonding strong enough for climbing applications?"
"Yeah! I mean, theoretical climbing applications. For, uh, industrial use. Not for people climbing buildings or anything." He laughed nervously. "That would be dangerous."
"Very dangerous. Also very useful in emergency rescue scenarios. Ever considered applications for disaster response?"
"I hadn't thought about that."
"Think about it. If your adhesive works like I suspect, it could save lives." I handed him my card. "When you're ready for internship opportunities, call me. Hammer Industries offers programs for exceptional students."
"Really? That would be—I mean, thank you! My Aunt May will be so proud."
He pocketed the card, bouncing slightly with excitement.
Three years early. Enhanced abilities already manifesting. Uncle Ben presumably still alive. Timeline divergence continues accelerating.
The closing ceremony brought Tony and me together on stage.
"Vision for the future," Tony announced. "Where technology solves problems instead of creating them. Where innovation serves humanity instead of just shareholders. Where former rivals—" he gestured between us "—become partners in building better tomorrow."
We shook hands publicly. Cameras flashed. Media declared "New Era of Innovation."
Privately, I knew this positive moment was calm before the storm.
Killian was accelerating Extremis deployment. Twelve unstable subjects were walking bombs. The Mandarin performance was building toward public demonstrations. And Tony's PTSD would worsen as pressure increased.
But tonight?
Tonight Hammer Industries had achieved public redemption. Technology I'd developed would save lives. Relationships I'd built would matter when cosmic threats emerged.
And for one evening, I could pretend that progress was linear instead of chaotic.
The void marks pulsed steadily beneath my shirt.
Seventeen percent corruption. Two years remaining.
But fifty thousand people had witnessed Hammer Industries' transformation.
That was worth celebrating.
Even if celebration was temporary.
