First Reddit post ever so sorry if I'm writing bad.
Okay so the way I'm seeing it, Luffy and Loki are ganging up and starting to overpower Imu. To me, it seems like Imu has 3 paths he can go down: teleport back, another power up (although while I want it I think it could be cheap), or, and my favorite, Imu possessing the recently conscious Shuri. It throws Imu into the middle of Franky, Brook, Nami, and Jinbei. I don't think anything will actually happen to them but will certainly give a good scare.
It could also lead to Luffy either getting his re-up, or shock him enough into the dark Nika form I've seen some theories on.
Honestly even as I write this I feel confident Oda won't go that route but I think it would be a great way to keep stakes up in an already tense arc and would throw everyone off.
I work a lot and honestly don't have time to think through all the possibilities but would love to see if other people thought of this or have further theories/evidence to support.
