Feeling guilty about his outburst, when Emily suggested fostering, Paddy has had time to digest the idea. Admitting he has over reacted, Emily is encouraged and asks Paddy to think it over. Paddy is proud that Emily feels so much compassion and pleasantly surprised by her ground work but he has a lot on his plate at the moment. Seizing the opportunity to air his worries, Paddy confesses to Chris that Zoe’s behaviour is getting more worrying. Chris wonders if it's because the following week is the fifth anniversary of Frank's death, and is forced to acknowledge that Zoe's problem is getting worse after Paddy tells him about the drugs she's been taking, as well as the amount of alcohol she's been drinking.
