'Downton Abbey' Actor Reveals When The Series Might Go Off The Air

Allen Leech, who plays Tom Branson on the series, recently revealed to People that some exciting situations are about to happen to his character in the fifth season.

"There are a couple of things coming up in the series that I'm bracing for, for my character alone," he said.

Even though he didn't say much else about his own character, he did reveal another character that will have an intense story.

"Downton is again in a period of change," Leech said. "The first socialist government comes in, and you have a very conservative house very worried about it. And there are great story lines for characters like Edith, and where she was left at the end of the last [season]. Is she going to be able to deal with the fact that her child is basically no longer hers? Some really, really great stuff."

Downton Abbey Season 5 is set to air in the US on Sunday, January 4 at 9 p.m. ET on PBS. Season 6 will likely air in early 2016.
