It is also gaining increasingly higher ratings in Australia and Canada. The show has won numerous awards.

| 35 | "A Wonderful Mammy" | Ben Kellett | Brendan O'Carroll | 25 December 2019 (2019-12-25) | 7.04 |
| Christmas has returned to Finglas once more, but the feeling is far from festive within the Brown family, and on James Larkin Court in general. Buster has his own problems to deal with, while Agnes has fallen out with Winnie, who accuses Agnes of not caring. Even worse, Betty scolds Agnes for giving Bono (who is playing George Bailey in a production of It's a Wonderful Life) money to buy something at school breaktime, Cathy refuses to trust Agnes anymore after reading her diary and Mark threatens to not get his mother anything for Christmas if she doesn't listen to Betty. Wallowing in self-pity at Foley's, Agnes wonders what life in Finglas would be like if she hadn't been born. Clyde, a man who presents himself as an "angel-in-training" and needing his wings, grants Agnes' wish, and shows her an alternative timeline, in which Hillary (now called Hillary Brown) lives at 92 James Larkin Court in place of Agnes, and the children (now Hillary's own children), their spouses, Buster and Bono have different names and stories, as well as Grandad being in a home, Winnie (now Winifred) recognising Agnes from somewhere and Sharon now being a nun. The Christmas tree this year shoots fake snow from the top. In the end, it turns out everyone was pretending to have Agnes's wish granted to surprise her. ||||||

| Winnie fears for her life when she hears the news that Peggy Piper the Pernod Poisoner is out of prison pending appeal, as she will have to give evidence again at the hearing.

The Brown family, Dr. Flynn and Father Damien begin to question if Peggy really did poison Peter, and Cathy creates a group campaigning to have Peggy exonerated at her trial. Elsewhere, Grandad has a mishap with his hearing aid, and Dermot and Buster are running a recruiting appeal for the Defence Forces, dressed as Army soldiers and having Buster wear an expensive rented tank prop - which he then loses and has to try and find before Dermot finds out. ||||||

A new year brings a new Christmas tree, and this year's coughing tree with a mask represents the COVID-19 pandemic. Meanwhile Agnes wins a competition to broadcast a speech to the nation following the Queen's speech, resulting in her falling out with Winnie, who was desperate to win.
