No idea, it's SNK ;) We don't know what Marley can do, Magath propably dead with most of marley officers(?), there are still warriors but who know what they will do(Zeke and squad), i wonder about next chapter maybe flashback time(sry for mistakes with english).
I'm not sure honestly. I hope Floch doesn't die though, I'd like to see a bit more of him. I think he's a pretty interesting character. I could kind of see Sasha dying after she spared Gabi in Chapter 102, but we will have to see!
Floch is becoming too interesting a character for me, so I hope he doesn't die. It's cool to see a main character whose NOT part of Squad Levi fighting on the same side as them; since we've been with the others since essentially the beginning, it's a nice breath of fresh air.
Speaking of which, I think it IS time to say goodbye to one of the core heroes. The 104th has been protected long enough and since Bertolt was an enemy (and Marco didn't have much of an impact besides on Jean and Eren), we have not seen any of them react to one of the 'primary heroes' dying in battle. I personally wouldn't mind if one or two were killed; I think Connie and Sasha are the two most likely ones to die. Out of the others, excluding Levi, Eren and Mikasa, the only one I think is safe right now is Armin since he has yet to be seen as the Colossus Titan.
