Wendy has been watching Stan for the past few weeks. Over this time she's developed a massive crush on him and stalks him whenever she can. She's been getting pretty jealous of stan and kyle getting closer (as friends) so she decides to talk with stan. she has already "taken care" of kyle along with kenny, cartman, Butters and many more so that stan is hers and hers alone.

Wendy: hey Stan! Can we talk? Preferably right now? I have something to tell you. (She sounds a bit off)
