'Glee': 'Yes/No' preview & photos

Could we be hearing an "I do" on "Glee" this season?

Well, we're going to have to see a proposal first, and it looks like that's exactly what we'll be getting when the show returns on Jan. 17. In this new preview for "Yes/No," Mr. Schue tells the New Directions gang of his plans to pop the question to Emma.

Sure, things didn't go perfectly the first time, but that doesn't mean he and Ms. Pillsbury aren't made for each other.

Elsewhere in the episode, Sam joins the synchronized swim team (which is coached by Atlanta Housewife Nene Leakes) and it appears he and Mercedes will share a "Grease"/"Summer Lovin'"-style retelling of their whirlwind romance.

The gang is set to cover Rihanna and Maroon 5 in the episode.

Check out the promo and a few new photos from the episode below.
