Dad and Amber are back together - and Amber's moving in. It's only temporary, until they find a bigger place, but the resulting chaos drives Millie, Lauren, Fran and Jake round to Mum's. And Millie has an ulterior motive - getting Craig to look after the hyperactive Jake as revenge for his annoying behaviour. She thinks it'll teach him to be a better brother - but Jake thinks Craig is pretty cool as he is, and starts imitating his teenage ways. Back in the confusion of the crowded flat, Dad's new website is bringing in lots of work, but his Post-it-based filing system has a major weakness: gusts of wind.
