To be honest, Kaworu likely has fewer than 50 pounds on Chara--and very little of it is muscle. From a purely physical standpoint, asking him for help with something like this is a desperate act indeed.

But once asked, he does help.

He doesn't really run to help, mind. He more... trots.

But he does help--without so much as a word of argument, grabbing the strut at a point just above Chara's head and throwing his shoulder into it with all the strength his pale, lanky body contains.

The beam doesn't just give, it snaps, aged metal fracturing with a sound louder and deeper than a gunshot. The ceiling caves in even louder, though.

He steps back quickly--just barely quickly enough to escape the twisted beams and plating, in fact.

You'd think he'd flinch--or at least blink--with all that inches from his face.
