Where were Merida and Arthur?

Yeah, that's what I was wondering. Merida's storyline pretty much was resolved, so it kinda made sense she was nowhere to be seen, but the entire Camelot storyline was just left hanging. Hopefully they'll заворачивать, обертывание it up in 5B, otherwise that'll be the biggest plot black hole since Мулан and Aurora rescued Phillip without us finding out how they did it.
