Alex: *nods* she invented having so many poker face there isn't an actual poker face. Only one person has ever gotten the best of her. 

And that was pure dumb luck!

Billie: *leans against Logan* at least we have here right now.

Darren: good. Can't have him trying anything on you gorgeous.

And you know that Alex will look at Billie and be all like. "Can I? Please? I think I've waited long enough since you've stopped me every fucking time."
And she'll think about it for like half a second. "Just don't make me have to stop you." 
God, Jackie will so fucking earn brownie points because Billie would actually let Alex lose it a little. Until she knew it was going to far. 

She doesn't like overstepping her boundaries because she doesn't like when people overstep the ones she has. And you won't scare her off. She'll think it's cool, even if it will make her worry a little
