He's too slow.

Too slow, too sluggish, too imperceptive to save those that are just out of reach, not fast enough to stop Isabel from being decapitated or to stop Eld from getting crushed or to keep Petra from getting kicked into a tree. Then he's not fast enough to save Hange as they get stuffed into the mouth of a titan, or Erwin as his head is ripped from his body. He may as well be a spectator with how slow he's moving, and no matter how hard he tries, he can't make a difference- he can't go fast enough, can't hit hard enough, can't get there soon enough.

But he's not too slow to save you from a titan's jaw. He pulls you out, all in one piece, and he's relieved until you look up at him with wide, confused eyes and ask, "who're you?"

Who're you?

Levi wakes up in a cold sweat.
