Wow, there were a lot of Kimberly and Billy episodes early on. Episode 12 was Billy and Kimberly episode, then episode 13 was Billy, 14 was Kimberly, and 16 is another duo episode. Not to mention Trini had episodes 11 and 15, leaving Jason and Zack with pretty much nothing thus far. I mean, Zack had episode 10, but Jason hasn't had one since the fourth episode.
