Will Maru rat them out? He's been a mystery to me so far. Like, on surface he's this quiet little guy, who needs them to feel validated and just wants some good friends. Under the sutface, he has these moments of psycho-like joy, whenever it's about the bombing they did.
And my man Tobio went overboard, sadly. And I don't really blame him TOO much. You gotta make those mistakes early in life to learn. Gotta control your horny - out of respect for yourself, if not for your SO.
