In the preantepenultimate (I looked it up) episode of Kyle XY, S03E07, “Chemistry 101”, a lot of things happen. Here are some of them: Kyle begs Cassidy to let Jessi join Latnok. Kyle and Jessi plan a pheromone party with magic crystals. Andy catfishes a girl on Coolzone to set Josh up with a new girlfriend after she leaves. Tom Foss isn’t in it. Stephen and Nicole are also not in it. There are three episodes after this. Where is Hillary?!
