Igor expended considerable effort to explain the key points to Perkins...
Initially, Perkins was confused, but later realized, exclaiming that he had confused himself with his storytelling, forgetting even such simple matters.
It's like someone who is fine at first but then starts boasting to others, talking more and more until they don't even know what they're saying, completely insane. That was the state Perkins was in just now, so he didn't understand many things.
Now that Igor had spent significant effort explaining to him, Perkins felt relieved.
Both Perkins and Igor admired Stan Sol at that moment because Stan Sol had been very quiet, without making a single sound.
Stan Sol wasn't annoyed by them nor found them bothersome; he just sat there quietly with his eyes closed, as if no amount of noise could wake him.
