I see a big brawl between Rifel and Eaters + The Two.
Meanwhile, Clare will attempt to euthanize the Conjoined Being. But she'll fail and the Conjoined Being will attack whomever is winning that other battle. It will be a massive, three-faction free-for-all.
Just when something decisive is about to happen, Raki will be all "OH HI GUYS WASSUP" and someone will try to squash him; Priscillia will take exception and, despite being starved, she's still the invincible big bad that forced all these other power ups in the first place; plus she'll be fresh.
Then we will see: Raki and Clare make eye contact. They will ignore everything else, specifically the huge monster battle in the background.
"Raki." Clare said.
"Clare." Raki said.
"Raki!" Clare starts to run towards Raki.
"Clare!" Raki starts to run towards Clare, but not as fast. Because he's just a normal human.
"RAKI!"
"CLARE!"
They will then collide midair and passionately smooch; something in the background will explode, possibly Priscilla.
...
yeah.
More seriously, I have a feeling there are going to be... I'm gonna say two last minute rescues, where somebody shows up at the very last second to block an attack or something; it will be the "surprise reveal" kind of cliffhanger. I think Helen will jump the gun for hers, so it won't count, but I'm pretty sure Miria will get one. Dietrich might be the other one.
I'm not sure how Priscilla and Raki factor in to this. I want the Raki/Clare reunion, but I'm beginning to think that it will be the last resolved plot thread of the whole manga. Priscilla will probably just provide creepy-little-girl dialog like she did during the Pieta shindig.
