So Dr Eva swallowed her pride and danced to Gangnam Style. Err, we guess it's one way to say sorry. Tonight we'll be catching up with our leaders as Sgt Mulcahy puts them through their paces in the gym with a military-style bootcamp. Professor Niall Moyna will be heading back up to St Joseph's in Dundalk to check in with with the kids. They're trying to get their step count up to 15,000, and he'll be finding out how they're getting on so far. Plus we'll catch up with our remaining leaders, Gavin and Deirdre.
