When a new frontman joins Craig's band, Craig is told he needs to buff up and look the part - or he's out. Lauren is stressing about whether her looks will please her date for the school prom, and Millie doesn't know what to wear for No Uniform Day - she hates the idea of everyone judging her! Everyone is feeling insecure about their appearance, and Fran's no help - if anything, she seems too confident, defying Amber by wearing her temporary tattoo to school, and inspiring Jake to do the same. Millie helps Craig get his self-confidence back - but what can she do about her own?

Millie and Lauren compete to give dad the best Father's Day, like they do every year. But when Lauren raises the stakes by getting a card for Mike, it's game on - who can show they care for their stepdad the most?

Determined to win the school's big Eco Challenge, Millie goes green and insists the whole family make do without the internet for a week. Mike's not hard to persuade, so off goes the wifi! Craig and Lauren are livid and join forces to out-green Millie until she cracks: no hot water, no lights, no heating. Dad is cynical about Millie's chances of changing the world, and when Fran finds out why, she takes him on a journey into his own past. When Millie's favourite band release their new video exclusively online, she's caught in her own green trap, and Craig and Lauren relish seeing the tables turned.
