'Ankh. I'm a Greeed. A creature of unlimited desire.' If he was going to be latched onto this man, he ought to be honest. If he was going to attempt to keep this possession going. He still wasn't sure. This was difficult.

'So you're a mystery. And you're a mess.' Maybe that was enough to decide the matter for him. He couldn't keep this body because entirely too many beings already had a claim on it and he didn't want to have to share. But Rei didn't seem to be resisting as hard anymore. He stops trying to rise and thrash and otherwise pitch a great big angry fit, and relaxes. 'You're not who I need, so I'm not going to stay. But before I go... you need to do something.' No, not 'could you do something'. This was negotiation, not begging. Really.
