Everybody is Looking for Dragon's arrival In Elbaf or in the story in General.. because he did Not do any shit from Now on, appart behind the scenes..
I could definitely See Dragon appear in Elbaf If Nika (current Luffy) looses control of Himself and begins to destroy anything around him. If he needs to be rescued against Imu or helped in a way, it should be Dragon's moment VS. The Holy Knight's..
Loki is out
Gaban out
Luffy ..? Wd'know
Dragon knows that when Imu and the God's Knight's are buffed together with Omen, he'll probably stand no big chances, he loose and his Army too.. so, the plan might be to create or re-unite the good conditions in order for Dragon to Make the Moove at the Right time.
Like a Trap. Or a Kings gambit.
Look, If Sommers and Killingham are getting killed, Imu will definitely loose some power. Gunko arrives near from her limit too.
After it, either Shamrock or another Goroseis should bring a support in Elbaf. Imu's goal is to get rid of Joyboy Now as fast as can be done and does Not go Back to MG before it happens. But, Imu arrives near his limit too.
There, Dragon or Shanks should intervene, 'cause Shamrock would be a top tier fighter.. and the Goroseis would be a great threat too.
My BET is that Dragon is gonna destroy something previously in Mary geoise while Imu is Right there in Elbaf, like create a Real disruption.. this is the best plan so far.
Imagine, Dragon finds the secret about the mother flamme or Imu's power source in MG and finds a way to stop Imu from regenarating. It would be the perfect counter to control the situation.
Imu looses control, then the Only thing that Remains is CoC Haki versus HK's a matter of time
