Yup, this week's episode centers on Katelynn, whereby all the cast members come to know her (but not in the Biblical sense). It finally comes out that Katelynn is a transgendered person, thanks to JD informing everybody behind Katelynn's back (“You didn't hear it from me!” he says at one point).
We also get to know Katelynn, perhaps more than we, the audience really care for, as we see her walking around the house in her underwear and see her practicing pole dancing. The rest in the house are scandalized at her walking around in her underwear, and are really scandalized when Katelynn does her pole dancing at a bar in Gettysburg (the cast is there to help with a bicycle race to raise AIDS awareness), especially since the pole is a structural member, not something used for dancing (and as much as I like Katelynn, this was very painful to watch … why Katelynn? Why?).
Now, while it's clear that Ryan is a jerk (or the show is edited in such a way as to make it seem that way), JD is coming across as the real untrustworthy one in the house. He broke Devyn's trust, and now he broke Katelynn's trust. So while Ryan may be a jerk, he's an honest jerk, if you know what I mean. He is what he is. JD … isn't. It'll be interesting to see how things develop with him over the remaining episodes.
