Have now watched BBOTS and can confirm the obvious fact that Luke's wife doesn't say that he wishes he was Luke S. As if. A random member of the audience does say that early on, but another random member of the audience then says that he thinks the problem is that Luke S is uncomfortable with Luke A, so fair enough.
Luke's wife says nothing more scandalous than that he wooed her with smooth talking, that he is closest to Adam, and that she doesn't mind him being transfixed by Lauren's gymnastics because she was the same. She also produces what Alice rightly says are the worst novelty slippers in the world. There is a pretty photograph of Luke-as-Laura on her 18th birthday and the same very nice wedding photograph that she has on her twitter. I challenge anyone to make anything untoward about that; indeed I see that in the WHATM thread sad bb addict specifically said that he/she likes Becki on BBOTS.
