I just thought the comment was in defence of Darcey who has been getting quite a lot of stick from people (on forums etc) who think she knows nothing about ballroom/latin dance.
And I find it really tiresome when Bruce has a dig at Craig, whether it's scripted or not. Craig is there to judge and give his critique. His comments are completely valid, even if they are a bit harsh sometimes. I'm sure Craig doesn't actually give a hoot about what Bruce says, and it's all done for effect anyway, but when Bruce says things like "oh don't take any notice of Craig, he's in a bad mood" it's actually very condescending. I wish they'd stop doing all the Craig-as-pantomime-villain stuff, it's got very dull.
