Gluttony was kicking himself because it would have so been worth losing his tongue just to make out with Lust. Well, he imagined making out. He didn't know what she would have done, so he was just pissy and angry at himself because he was being a fucking wimp.
He could be heard cursing at himself as he searched under the bed. At Greed's comment he shot up from under the bed and pointed threateningly at Greed, "FUCK YOU, MAN! AT LEAST I SHARE. Sometimes."
