Eren still hasn't said anything about how he thinks he may have activated the power of the Progenitor Titan for the first time. I really think he should at least start by talking it out with Historia in private, and they can also test it out in private and see if they can get it to work while she's still just human. If anything, him keeping his mouth shut from everyone in an attempt to protect her and the people she's supposed to govern could backfire and do them more harm than good.

Plus, something tells me she won't even need to be turned into a titan or shifter anyways, as I think it will be not Historia, but Zeke who ultimately helps him out with using the full power of the Progenitor Titan and putting an end to everything. It could be that Historia isn't even a Fritz, but can still help to some extent for being a Reiss, but it's the Fritz line they really need for the full power in the end. Maybe being closely related to that Fritz will also help with tapping into the power, as might that Fritz being not just a mindless titan, but a titan shifter.
