While sharing a quiet Xmas together, Nell and Addy meet Addy's newly divorced neighbor Dennis and immediately start competing for his affections.
This episode is more enjoyable than the Season 3 offering where Nell was so nasty. She pulls some tricks here too, but so does Addy so it's more balanced. To be honest, this one could have taken place anytime without the Xmas backdrop and it's heavier on the comedy and very light on sentiment.
It's funny when each tries to make the other look bad in front of Dennis, but behind each other's back. Addy bluntly tells Dennis (about Nell) "She has four kids and lives with a cop". Nell secretly tells Dennis that Addy's a kleptomaniac. Nell throws the Xmas tree off Addy's balcony and their behavior is such a turn-off that Dennis leaves a note - stating he's returning to his wife to beg for forgiveness.
Life I said, it's not very festive but it's probably the best of the four Xmas they made. 6/10.
