Gokudera moves to loosen the collar as much as he can, then lifts it up so it isn’t touching his neck, waiting for Ochako to get a hold of it with her magic.

“This isn’t a one-time shot.” He says, hoping to ease some of the girl’s nerves. He knows that it’s a life-or-death scenario, but if he uses the potion and her grasp on the collar falters, and it shrinks with him, it’ll be a failure, but not a fatal one.

As tricky as it may be for him to get his hands on more pixie dust to get a new shrinking potion from Emet-Selch, it’d be easier than being brought back to life.

Not that he expects that. He has to keep reminding himself to remain positive.

Despite the nerves, he’s seemingly relatively calm about this.

Gokudera won’t be drinking the potion, but pouring it over his head carefully. Still, he uncorks the bottle while holding his collar up, waiting until it is secured in place with magic and still completely oblivious to this procedure.

“Got it?”

Not asking if she understands, but if Ochako has the collar secure. If it starts to tighten, she’ll feel it pulling in her “grasp”. So far so good, though.
