 I may be way left with this one but it's just a theory, nothing more. I believe the quadruple titan is Marcel, Reiner and Bertolt's friend from the homeland who was eaten by Ymir. We've seen a big deal of plot armor from Isayama throughout this last arc with Reiner surviving on multiple occasions so I won't rule out the unordinary with this. Ymir is no where to be found and Reiner had a note from her addressed to Historia of which we still don't know the contents of. I believe Ymir offered herself to the homeland through some type of sacrifice to resurrect Marcel using her body as a vessel. Since she did have his (titan?) dna within her from eating him, I wouldn't rule out some strange homeland procedure that could do this. Whether this is true or not, I believe the identity of the quad titan will be revealed soon as a replacement for Bertolt.

 For this same reason, I don't think we've seen the last of Bertolt. His death was rather abrupt and left us with unanswered questions or a dramatic send off the way Erwin and Armin had before their supposed deaths. I don't think he'll take over Armin's body or anything drastic, but perhaps be able to communicate with him still?

 I realize this theory is super far out there but what do you guys think?
