I imagine it would depend on how he treats her daughter and if he snoops around their house at all of course. Marideth wants someone to help her daughter and talk to her, since Illya refuses to speak to her mother about what she does for a living since she wouldn't teach her any of her thief tricks. Even though Marideth is pretty cold, she tolerates his presence and would, as he said, poke fun at him from time to time.

I can agree with that. Of course, they both have a habit of throwing knives at him as well when he gets too flirty. As long as he isn't as bad as Ezra they won't tear out his tongue.
