Zenith hesitates a moment. She said that he should go to sleep… but if he's going to protect her, he needs to be awake. Sure, he's a light sleeper- but that half a second it takes him to wake up could cost her life.
The teen sighs. She'll like get upset if he doesn't sleep, though, so… well. He could just pretend to sleep. Yeah, that should work.
So he makes his way over to a run-down couch and lays down, eyes mostly closed, to the point where any onlooker would think that they actually were. He relaxes himself so he appears to be unconscious, but in reality, he's paying attention to every miniscule detail of what's going on around him.
Which is why, three hours later, he doesn't miss the soft creak of a floor board. Still, he doesn't move a muscle, choosing instead to spend a moment gathering information.
One person, three types of knives, a pistol, and quite the stealth skill.
Then he jumps up, drawing his katana. The assassin immediately notices him, but before they can make a move, Zenith starts talking.
"Hey Ev!" He calls. "I don't suppose you invited any company over?" Its not a real question, just him trying to alert her of the situation.
(Lol sorry I love combat scenes if you want less of them just let me know and I'll stop)
