I believe that the beast titan is Grisha. They showed this chapter right after revealing the face of somebody with some... similar but distinguishably different characteristics that prove nothing so far.

But I mean... the way Keith met Grisha signals the obvious idea that Grisha was a titan, and the fact that he rememebred things abotu him self, such as being a doctor, would mean that he's picked up memories of, perhaps, before he was a titan?

People have said because the beast titan didn't know about 3d maneuver gear, he couldn't be Grisha, who obviously knew about them. However, titan forms appear to have a very different pickup of memory, so just like how he forgot who he was after turning back from being a titan, he could've experienced what Eren did with that difficulty to think and remember things. Sure, the beast could even talk in his titan form, and looked like he was all the same after he came out of his nape, but we don't have enough info to really be sure.

I did also want to mention about how the beast titan knows those things about the mysterious "Warrior village" like Reiner Bertolt and Annie do. If Grisha came back from being a titan when Keith met him, the last time he was human could have been his lifetime in that village, as a doctor (no one in the walls ever knew about him anyways).

Also, it appears in this chapter that Grisha entered the walls very uneducated and unknocwing about anything within them. Well, howcome he seems so smart and educated later on, let alone having a deep secret in his basement? Treating people in the walls as the doctor he once was must have started tirggering him to pick up more memories of himself over time, eventually leading to his recollection of who he may be (the beast titan from an old village).

Just my bet that the beast is Grisha (and I think that would lead to very good plot).
