A new face rocks up in Carrigstown tonight as Paul's son Oisin turns up at the Brennan's door. Last time we saw him he was only a wee one but he certainly isn't that anymore. Rachel and Paul are delighted to see him but Niamh is convinced something is not right and worries why he is really back. Spoiler... she's right to be.
There's another arrival in Carrigstown too but this is a face we know well as Dan arrives back from London to sort out a few things. Carol however is soon concerned over whether Dan is happy over there as Sally works a lot so he spends most of the week by himself. We'd be inclined to agree but Dan soon convinces Robbie otherwise.
Also tonight, Emmet starts to turn his attention to Ama, much to Doug's annoyance, while Charlie is annoyed that the historian booked in for the 1916 talk has cancelled, so Cass offers him his play instead.
