Since it's been a few years, Sergeant Grace changed the school into a military school. Abbie has been resucitated, and so has Lana. Lana always talked to Abbie, which, at the time, you didn't know kept him stable.

Lana has been away for about 3 days now, and you find Abbie sitting in a classroom, he seems like he's having a breakdown...

Abbie: "Why... WHY ALWAYS ME?! WHY AM I ALWAYS KILLED?! IT'S SO UNFAIR!"

He's crying, breaking down, poor dude...
