Read what’s coming up in the next three episodes of How I Met Your Mother, titled “The Over-Correction” and “The Final Page,” parts 1 and 2.

Previously we reported the brief descriptions of the three episodes, and now CBS has issued more detailed press releases for the episodes (as reported on SpoilerTV).

The synopsis for Monday’s episode “The Over-Correction” reads:

ROBIN BECOMES OBSESSED WITH BREAKING UP BARNEY’S RELATIONSHIP WITH PATRICE, ON “HOW I MET YOUR MOTHER,” MONDAY, DEC. 10
CHEAT TWEET: Robin’s romantic life is stalled with Barney and Marshall’s mom is moving on romantically #HIMYM 12/10 @8PM ET/PT http://bit.ly/SvLewZ

“The Over-Correction” — Robin becomes increasingly suspicious of Barney’s relationship with Patrice. Meanwhile, Marshall discovers his mother is moving on in her romantic life… with a very disturbing partner, on HOW I MET YOUR MOTHER, Monday, Dec. 10 (8:00-8:30 PM, ET/PT) on the CBS Television Network.

The following week is the special one-hour episode titled “The Final Page.” The official description offers us some clues about what to expect:

AS CHRISTMAS APPROACHES, TED WRESTLES WITH THE DILEMMA OF TELLING ROBIN ABOUT BARNEY’S PLANS TO PROPOSE TO PATRICE, IN A SPECIAL ONE-HOUR EPISODE OF “HOW I MET YOUR MOTHER,” MONDAY, DEC. 17

Seth Green (“Buffy the Vampire Slayer”) Guest Stars as Daryl LaCorte, Marshall and Lily’s Acquaintance in College, and Peter Gallagher (“The OC”) Guest Stars as Ted’s Former Architecture Professor

CHEAT TWEET: Something BIG is going 2 happen in this special 1-hr episode… somebody will be engaged #HIMYM 12/17 @8:00PM ET/PT http://bit.ly/R5pZ8a

“The Final Page, Part One And Two” – With Christmas fast approaching, Barney tells Ted that he plans on proposing to Patrice, which leads Ted to debate whether or not to tell Robin. Meanwhile, Marshall and Lily run into an acquaintance from college, on a special one-hour episode of HOW I MET YOUR MOTHER, Monday, Dec. 17 (8:00-9:00 PM, ET/PT) on the CBS Television Network. Seth Green (“Buffy the Vampire Slayer”) guest stars as Daryl LaCorte, Marshall and Lily’s acquaintance in college, and Peter Gallagher (“The OC”) guest stars as Ted’s former architecture professor.

Barney is proposing to Patrice?! We’re guessing this is all a big ploy by Barney to make sure no one learns of his real plans to propose to Robin… what do you think?
