Well, I half-called it; thought Lewis was going, but I imagined it was going to be him and Bal. I think he and Katya both came across as very sore losers. Although what was Amber on about, them being her biggest supporters? 
Bal will go next week, sadly. She looked like she genuinely didn't know they were doing two dances!
Loved Karen's reaction to going through.
Quite liked the Cell Block Tango routine, and Karen and Luba were hot stuff.
