Mantis would have never expected this: that he would be working side by side with Raze in trying to break out of a facility they were captured in by the Light Faction. He could see Raze doing something as he placed both of his hands on the ground.
"I just had a thought," Mantis said. "Why did they just capture us and not the others, and what's even happened to the others?"
Raze had already thought about this, considering a large number of different things. He was hoping they had all managed to escape, leaving behind the two people that weren't able to fend for themselves.
As for a reason why they might still be alive, both Mantis and Raze had shown extraordinary abilities. Mantis with his body being partly a beast and a Hybrid, and then there was Raze and his magic.
