Maybe, crazy thought, but perhaps we haven't seen the last of the 'Reiner's split personality' plot device and that it's going to re-enter the story in an unexpected way... Perhaps, because he was fighting on the side of the homelanders rather than posing as a soldier when he was attacked, perhaps 'Reiner the Warrior' "died" when his head got destroyed by the Thunder Spears, and only 'Reiner the Soldier' comes back, with... interesting results. If that happens then reiner is definitely going to return back to my favourtes list.

Actually, If you think it like this way, It  makes more sense. Reiner SP had no real use from the start. It was just mentioned  here and there and also He didn't have a slighest bit of hesitation at every battles. He was clear minded (mostly) and fullfilled his duty. Now would be a best time to put that SP of him to good use for HUMANITY.
