Well, robes have become sort of a status symbol in the house. Janelle has an expensive robe that April really admired, and her husband bought her an even more expensive one that she got when she won HOH. Beau lived in the HOH robe and I can't remember what Maggie did, but I just have a feeling she or Ivette would be wearing it all over if they had won it.
Also, I can see Janelle sleeping in by herself in the HOH room while Howie would be happy to go to the Gold Room by himself. The other 3 would stick together in the subway room or the HOH room, either way. Howie and Janelle usually get up at the same time, which is why I think they didn't sleep in the same room.
I'm just rambling now.
