Soldat's main job has been accomplished, and he'll sit and make smelly body-snatcher (and their new friends) a bunch of origami in thanks, and let Weaver know that maybe if she makes overtures they might be a useful ally. He'll apologize to Weaver on the failure to remove the bodies, but try to reassure her that the spirit is treating them with affection and reverence, and speculate that this particular spirit and their new companions, might in fact be one of her former coworkers, since they insist on calling them "friends". He'll also patch up Link's foot until Law can have a look at it later.

Then he'll play backup for whatever anyone else wants, maybe help Will and Rosi poke at the world eater corpse if there's time for that? He'll offer the metal arm to touch it pieces with, if need be, since that's prooooobably safer than flesh, and also he heals faster than the rest of you. If he can get close enough to even do that, that is.
