Will will never know, unless there's a new series called Father Hathaway.
I'd watch that show
I felt the balance between Laura/Robbie's relationship and the partnership of they dynamic duo was perfectly split. We know they're together and happy, so there was no need to bash us over the head with it - I loved the scene where they were cosied up watching tv.
Agree with everyone else who loved the final scene. It did kinda feel like it was the end, but like someone else said up-thread, we heard them talk
about leaving but we didn't actually see
it. On that basis I'm going to hold out hope that they at least come back for a Christmas special or two in the future.
