Sarah (per Wiki) decided to lose her Virginity to Peter, and Peter decided to help her. The only thoughts, either Sub- or Fully-Consious on Peter's part were "getting a piece"...of the action. (Gotta stay clean, here)
The reason that he made Sarah ( in both senses) was because he was deficient in the Werewolf "Birds and Bees" education to the point that he didn't connect having a good time with making a thrall.

That lack of knowledge, by the way, saved both their lives...
I have to wonder, though: back at the beginning of the Story, the Sheriff is telling Gus that the only reason he's alive is because it would be too hard to hide a Deputy's body... how would they have hidden Peter and Sarah's bodies?

I suspect that Peter is still not up to speed in the "Mated for Life"* bit, and neither is Sarah...after all, it's been less than forty-eight hours since Sarah first Wolfed out in the PiTW universe.

As for Choosing a Mate: I suspect Peter would have gravitated more to someone like Jean (not Jean herself) simply because he connects friendship and good times with a slender, sexy dark-haired female lilkle Jean Goodwin. Jean herself (per Wiki) has other aspirations for a significant other; and Peter isn't it. Still, I wonder what Becky has in mind for Peter...she's still after him.

As for nurturing and protecting Peter; why didn't Sally give him the facts of life when she saw her mate wasn't doing so...and why did she let Walt grind Peter's ego into nebbish-land? There's more here than meets the eye...or has been drawn. Only Kris knows for certain, and he ain't saying--so far.

*"Mated for Life" applies only within Peter's home pack's territory. I suspect that if he leaves that area, both he and Sarah will be free to choose. It'd be a hoot if, after all this, that they actually did come to care for each other...
