Dont pretend you're not wet.

I agree with Icecakes that as it was shown, Coleen seemed unaware that Julian was going to do it which is quite a liberty (sexuality does not give anyone the right to be sexually inappropriate). Also Colleen said something like "No, I'll put it in" to which Julian replied "No I will" and shoved his hand down. Hovever, as Lorenzo disclosed on being evicted, that whole task was very heavily edited, with 15 items actually being discussed and not 10. It's likely that as well as cutting out the other 5 items, C5 cut out the bit where Colleen and Julian would have discussed what would be funny for their viewing customers to see. That would also make sense of Julian tipping that gunge all over her face and down her top, as I doubt he would have done it without her consent. I don't even like Julian, but the shown task did look uncharacteristic otherwise.
