And, as always, Cartermatt.com has some nice teasers in lieu of blatant spoilers to pique your interest for this week's episode. What big plot points should you be on the lookout for?

-Look for Thomas to take a liking to new footman Jimmy. Is his interest purely professional? But of course! When has Thomas ever had an ulterior motive?

-The somewhat overwrought Anna+Bates saga will continue after last week's letter-getting frenzy. A surprise revelation is in store that will change the lives of both characters, but will it be a change for the better?

-Though these angles are titillating, there is still one MAJOR bombshell to be dropped tonight. Does it have anything to with Sybil's pregnancy? Is the christening controversy going to boil over into something more?
