Ok, I was pondering this and I came upon a prediction that would be just shocking and morally ambiguous enough for Isayama to actually follow through on this...

Reiner, with the 'soldier' split personality comes out of the armored titan in Shiganshina up in flames. He is disoriented, has no idea what is going on and is in utter horror. He is found by the rest of the survey corps and he addresses them as his soldier personality in good faith because he lost his 'warrior' personality when he moved his memories to his titan brain. Levi and the rest of the survey corps think it is all an act but at the same time perceive him as very disoriented and defenseless.

Then Levi gives the titan serum to someone, or uses it on himself, seeing it as their chance to simultaneously get rid of the armored titan and gain his powers, and Reiner dies, in abject horror and not knowing that he's actually capable of transforming as the survey corps' "interim titan" eats Reiner.
