[Honestly? Gundam doesn't mind talking about it. Not with someone who could technically be considered a classmate. Perhaps not from the exact same class, no, but the same school? It's close enough. Considering he's likely Leon's upperclassman, there's a chance he'd know about it anyway.

It's not like he's ashamed of it, after all. He's fully accepted what he did, and the only reason he'd avoid talking about it would be the sense of respect and loyalty he has for the other students.

If he talks about his part in the murder game, whoever he's speaking with would eventually wonder about the others.]

Enough to know you required assistance, but it would be hard to tell if I had heard "all of it" without knowing what "all of it" entails.
