Looks like an older, scruffy Eren doing spy work. But how does he keep his leg from regenerating?
Maybe he learned, like Reiner when he kept his arm from regenerating in the chapter when he was bitten by a titan trying to save connie, maybe...

In order for Eren's leg to grow back he needs sunlight just like the titans need sunlight to move. If he keeps his leg covered, it won't regenerate. (⌒▽⌒)
Ah, that makes sense. THANKS.
Eren? Is that you? *0*
