Well, not every plotline is wrapped up, but "Downton Abbey" comes to the end of its fourth season with members of the Crawley clan trying to keep the Prince of Wales from getting mired in a scandal — and not the one that forces him from the throne in 1936. It's a rather low-key season finale otherwise, but it will leave you anxious for Season 5 in 2015.
