So, what - he's just not gonna actually speak up about wanting to fight as well?
The longer that goes on, the worse it's gonna be for all of them, because they'll also likely feel like shit if he bottles it up and lets it fester until the truth comes out at the worst possible time in the most toxic way.
And now that his weird skill whatsit is talking to him again, I can't help but imagine more hardship will be on the way. Continuing this reluctance to be upfront and honest might become actively dangerous, in that event.
