I think he's dead. Remember the FL said he was one of the first bitten by his friend and turned into a zombie by the time she went into the music room. So since she didn't go and save him, he's most likely dead this time around as well. But it would make a good plot twist if he somehow survive ╮( ̄▽ ̄)╭
Yeah I think it didn't matter what she did, he would get bitten or something would happen to where he wouldn't be saved. And even if she somehow managed to save him from being a zombie, the ML don't seem like the type to handle a zombie apocalypse like not wanting to kill the zombies or just not even thinking and going crazy.
I HOPE HE'S STILL ALIVE ༎‿༎
