Colin blinked a few times as Zach started sniffling, gently pulling him toward the couch. It was likely a bad thing for him to bring up, but he had to bring it up. "Shhh...It's fine. Nothing too dangerous." Though, the definition of too dangerous tended to vary and he couldn't promise it wouldn't get there without him meaning for it to.
He pushed him down onto the couch, moving to sit in his lap as he did. "I'm right here. I will do everything in my power to stay out of very dangerous situations. If dangerous situations happen to me without my being able to predict them, though, I can't really do anything about it."
He just let himself sit there with him. "There's only so much I can promise, because if I promise too much, I'll feel bad if it happens...and then..." He shook his head. "W-we can talk about something else if you prefer. Anything you want."
