Having seen the performances, I think Stephanie could well be in the bottom two this week. Mr Bojangles is a notorious vote-loser, and her rendition was far less good than Sarah Lark's on IDA. Probably the weakest performance in any case on an exceptionally good night.
The other is harder to call. Steph, Danielle and Lauren must surely be safe, but I think any of Jenny, Sophie and Jessica could be possibles, and I don't think ALW would save any of them over Stephanie. I really hope it won't be Jenny. If I had to say one, I'd say Sophie.
