Either option is honestly precious as fuck, and matching good luck charms- he would keep it somewhere close on him because she's already broken in to that soft spot he still has despite all of his protest and denial and gruff. Definitely will not be something easily hidden if attempted since the initial injury is going to be enough to put him on bed rest for a bit, and then needing to take it easy despite how quickly he heals and ho much he can endure and tolerate pain-wise.

How do you slow a super soldier down? Nearly kill them, apparently!(Honestly he needs to.)

He'll keep himself as someone to lean on at least and he'd be glad to know he helped at all. 16 is a confusing and hard as hell time, and he remembers that much and would damn well believe could be even harder for her.

Yes, yes good. Depending on how it goes he might have to bounce between the two because he sure as hell can't go right back to the woods after Nearly Dying, fffff.
