OMG, I was just watching Desperate Housewives on Seven and a promo aired for Episode 5!!!
The promo started with Paul talking about his high IQ and then showing some clips we have seen from before of Paul saying that if another team is in his way, he will "bowl them over". The promo calls them the 'villains', and then there's a scene of teams just sitting around and then Paul & Steve show up and Grace asks Paul for a Hi-5, and he says "No, thanks".
Then it switches to a clip of several teams running around in the dark, and you can see Michelle & Jo and Lucy & Emilia running and then you hear a woman screaming and they say that Paul pushed/hit Grace or something and she and Joseph looked angry and the F/F teams were there as well.
This is shaping up to be really intense...
