Carson, Carson, Carson. Just what are we going to do with you?!

In the latest trailer for Downton Abbey, Carson totally breaks relationship etiquette when he allows his worries about others to override how much he cares for Mrs. Hughes. "You don't think maybe you should start calling me Elsie?" Mrs. Huges Elsie asks.

"Not here," Carson says, aghast at the notion. "Not while we're working!"

Downton Abbey returns Sunday, Jan. 3 on PBS.
