The end result of Kellen rushing the others into the safe room meant that he was left with about seven people who couldn't fit into the space. That included Brent, Kellen, Sergei, two Guides and two Espers. The two Espers were S Classes that had been amused, and then impressed by Kellen's techniques and had continued working out with him while also not so subtly asking when he'd be able to send his students out.
Of course, they would take advantage of Kellen as they could at the moment, but Kellen had a firm stance of not sending his people out into war zones when most of them had chosen that they did not want that path.
The Espers had been mildly upset, but understood as a fellow S Class what Kellen was saying. Now that Kellen found himself in this situation, he was glad that he had them with him. He couldn't remember what powers they had, but given that one had glowing silver eyes like Sergei and the other had a more true grey eye colour, they were powerful in their own right.
