Well, I can edit to have him not leave yet, but if he's gone, then he misses their reactions. ^^ Not that I want him to miss them, but if he leaves, then he has to miss them, people who are miffed and enraged tend to miss the calmer side of things. He needs time to cool down, seeing the colonel after everything, he's just a bit too outspoken with his opinions and thoughts to avoid it and calm himself down before things go down.
Sorry he won't be there to see the others react, but he was already on his last nerve, he couldn't sit in that room for much longer, so he left. No time to process what he'd seen and what happened to him, so he walked out. ^^"
