[Ren could be really rude and mention the last time Molly tried to take his mind off things with recreational drug use, but he doesn't really want to open that back up for discussion right now. Especially since he already expressed that he's willing to watch over Molly doing it even if he's not the most interested in partaking himself.]

Well, anything that sounds like a challenge is good for me...there are definitely other things I could do to you that I didn't get the chance to yet.

[Granted, a lot of those things require a lot more preparation and probably at least a little bit of advance warning, but he'll cross that bridge when he comes to it. As it is, while he does entertain the notion that he's not as distant as he pretends to be and that might be a risk when it comes to something like casual sex, at the same time knowing in advance what kind of person Molly is helps, because the last thing Ren would want to do even if he did start having other feelings would be tie someone down who didn't want to be.]

I hope you're not expecting me to regale you with exciting ideas right now, though, I'm too tired for that...
