He wasn't supposed to explore alone, and Levi generally agreed with that one of SecUnit's rules. But he was a combatant, so it didn't exactly apply to him. And he was going deeper into the creepy, gravity-twisting hospital for the purpose of finding others who had ignored that rule and gotten themselves in trouble. (And loot supplies, of course.) He mostly avoided the restraint systems and monsters so far, though being ID'd as "Infected" was really annoying. He didn't need the hospitals telelectroscope whatever the fucks telling him that.

Spotting and avoiding traps on the ground (or whatever surface he was walking on) was something Levi'd gotten good at but he didn't expect them from the ceiling. Even if he should have, because it was the floor right now. A pair of straps shoot out from above and grab an arm. Levi tries to jump aside, dropping his gun to slash at the straps with his claws. The restraints aren't designed to go all the way to the ceiling and back so they don't have the best grip on him and he's able to claw and wiggle his way free quickly.

But not quickly enough, because the second strap held a needle instead of a cuff and it has enough time to inject him before Levi retreats to the next room. He's sweating profusely and some sort of black plates seem to be forming on his arms.
