Law & Order: UK
8x08 Repeat to Fade [series finale]
This certainly feels more like a first episode than a finale -- and, as they've now decided to "rest" the series (i.e. "cancel by any other name", I should imagine) it's even weirder.
[Watch it (again) on ITV Player].
Some Mothers Do 'Ave 'Em
2x05 Father's Clinic
The one with the famous rollerskating sequence. The rest of the episode doesn't have as much to recommend it, unfortunately.
