Listen to the girl.

Malrick stretches, "Sit down, just tell me what's wrong." She sits in a chair ext to him, "My friend and I were taken by crazy people, I managed to escape but they still have my friend. I need help to get them back. I can pay you."

Money, it makes the world go round. He definitely wouldn't mind deepening his pockets a little. But did he truly want just money out of this? With how desperate she seems he probably wouldn't have to use much effort to talk her into bed in exchange for helping her. Or, he could just do it as a favour. Good karma and all that.
