Trowa had picked up his mug and nearly taken a sip of coffee when Duo made the comment about Quatre being a fun drunk. Thankfully he hadn't, because he was fairly certain the hot liquid would have gone down wrong. "Depends on your definition of 'fun', I suppose. He's certainly less diplomatic when he's drunk, though he waffles between languages when he does. It's quite entertaining to hear him rant about inane things like his sisters' habits with the occasional swear word in whatever language pops into his head."
