"Only the ones that would look good tied up on my bed with a gag in their mouth."

"I think your roommates might have a thing or two to say about that," which is deliberately not a no. 

"But there are lots of woods in this camp. Lots of places where no one would hear you scream."

Serena is lurking around the edge of this conversation. It is, in fact, technically heterosexual and that is the point of the camp, and Ghost seems to be fine with it. But.

"Gosh. And here I thought I'd have to ask nice." Serena's lurking hasn't escaped her attention, but she doesn't especially care. 

"Oh, I don't care whether you ask."

Raine leans forward. "Even better." 

She taps her tongue against her front teeth. "I liiiiiike you."

"I like you too." 

The extent to which this is playful flirting and the extent to which it is sincere is left as an exercise for someone who is not Raine. 

"So, wanna skip group and go, what was it, develop the capacity to function heterosexually?"

That is quite enough. 

"Harriet!"

"Sorry, I mean, after dinner. Group's important."

She's visibly trying not to laugh. "I would love to, what was it, develop the capacity to function heterosexually. After dinner, of course." 

"Harriet, True Directions is not an appropriate place for sexual activity."

"Wow, are you wrong there."

"We are supposed to be learning how to function heterosexually, though. We're not going to have sex, I'm just asking Harriet on a date to the craft building." 

"I suppose," she says in a skeptical tone of voice. 

"You do want to encourage us to spend time together outside of group, don't you? And I'd love for us to spend time"-- she licks her lips again-- "together."

Serena cannot actually think of a way to object to this.

Good. 

"So it's a date?" she says to Harry, two-thirds joking. 

"Ab-so-lute-ly. The craft building's a wonderful choice. If there's one thing I like more than rope it's needles."

"Oh, good." 

Harry absolutely would be threateningly tracing her fingers down Raine's jawline right now, except that Serena Joy has with a great deal of effort taught her that this is Not Appropriate For Group Therapy.

"I'm so glad there's someone fun here. Everyone in my group except Sinead is so boring."

How about she doesn't put Harry's attention on Lev or Marlo. "Glad I found you, then. I was starting to get a little — frustrated, shall we say — myself."
