Immie is attacked in the street for her phone. The guy scrapes her skin with a needle. She then gets very panicky over going out, and has to get tests for among other things HiV. Rob and Karen jeopardize their jobs as they try to find out who the scumbag was, and Karen doesn't handle it at all well. Bored while out with baby Joe, Zara joins a mothers exercise group 'Mothers Kicking Ass', and gets very competitive.
