It's not the worst Torchwood episode, but it's not good and definitely feels like a step back towards the first Torchwood series. It feels like a very silly use of sci-fi tropes when I was actually excited to get into a story about Rhys and Gwen. These two have had a rocky relationship to say the least so I figured this would be a way to build them back up together again, while acknowledging this should mean a change in the status quo. It felt like it should have been a big moment, with Rhys becoming more integrated with Torchwood and now him fully committed to Gwen, this should signify some sort of change in the characters and their lives. And while that is, to a degree, true of the larger show, Something Borrowed feels we make a bunch of jokes that I just didn't find funny and we're left with an episode I simply did not find purpose in. It feels especially out of place after such a heavy trilogy of episodes dealing with Owen.
