There probably is an element of truth to it, I thought like most that they had a professional relationship which produced a couple of competent routines, for most of their time on the show. There defiantly was a problem during the last week which may have been because of his twills or for other reasons.
Interesting to see if she turns up to the final, I'm sure that they will make the most of it, get through it and never contact each other again.
Is it damaging to their professional reputations. Maybe, or it may be forgotten about in the next week or so.
