It was part of the recent series, but was dropped due to an ongoing trial at the time of intended broadcast.
Wondering whether the episode may have been re-edited slightly regarding Leo's series story arc?
Agree it was uncomfortable viewing at times.
Ah I see, I think I remember something about an episode being dropped alright. It was alot more watchable than the last series which I actually stopped watching as the episodes got more and more ridiculous, this is more like the old Silent Witness IMO.
