I've always liked the imperfect togetherness of Gwen and Rhys and I thought they were perfect here. I also like that the went into some sort of witness protection like hiding, and that they are both so obviously conflicted about Gwen's Torchwood past.

The Owen Harper comment (and that scene in general) were so very wonderful and really made it feel like Torchwood series 4 to me and not a new show.
