The ratings should be good this weekend as there is no SCD. If they are not then the alarm bells will be ringing.

its got casualty 30 against it - see how that effects it. Shouldnt really but they completley clash - personally ill be recording x factor

It's a bank holiday with added competition, nobody will be expecting much for this weekend. next Saturday will be more interesting.
Of course, this episode could timeshift plenty too - ~2.5m is possible.

Stick to raving about Fleur. You obviously don't know much about ratings.
