Same here. We were both disgusted when that happened, and turned it off. Now we don't care who killed Bunny.
The demographic for this series is probably older, middle aged, viewers. People who are very likely to tune out because of one of the characters turns lesbian.
My wife and I were wondering and were suspicious. We were kind of expecting it since it seems to be the thing to do with modern TV series... for shock value, introduce a lesbian relationship during season 2.
