Christmas Special: Shining Mammy - S0.E26

It's Christmas in Finglas once again, and this year Cathy has a new boyfriend, Boris. A last-minute change of plans leaves Agnes babysitting the widower’s twins while he and Cathy head to Foley’s for a quiet, romantic drink. Not everyone is convinced he’s right for Cathy, and there are even suspicions that he might be a vampire. But it’s not Boris that Agnes is worried about; she has her own concerns over his creepy twins.
