The 13th episode of "Glee" Season 4 airs Thursday night at 9 p.m., ET, on Fox. If you cannot get to a television, you can watch a live stream of the episode here, but please, click on that link at your own risk.

As TVLine notes, last week's "Glee" featured the characters channeling their inner divas. In Ohio, interim New Directions leader Finn (Cory Monteith) joined forces with guidance counselor Emma (Jayma Mays) to help improve the group's confidence and performance level before Sectionals. Emma, meanwhile, was a bit overwhelmed preparing her upcoming wedding to Will (Matthew Morrison), who has been in Washington, D.C., fighting for arts education in schools.

At the end of the episode, Finn helped calm an obsessive-compulsive Emma as she had a panic attack over her wedding details. Finn then kissed his mentor's fiancé on the lips, throwing the potential Wemma wedding into doubt.

However, based on Morrison's interview with TVGuide, it appears the nuptials should go forward as planned.

"I think the wedding is going to go pretty smoothly, but I think there will be some aftermath [from the kiss] in some episodes to come," the actor said. " ... It's going to be a nice big feud for a couple episodes."

There may be more than one wedding in Thursday night's "Glee," however. Creator Ryan Murphy tweeted a cryptic photo last month that shows a female in a wedding dress. The woman, shown from behind, has short gray hair, leaving many to suspect that this bride is actually cheerleading coach/New Directions nemesis Sue Sylvester (Jane Lynch).

Lynch spoke to Access Hollywood in January about the picture in question, but she remained coy about any "Glee" wedding plans.

"Well, if you recall, I married myself in the second season, so perhaps I'm renewing my vows to myself," she said. "I don't know. I can't tell you, it's a big secret."

Even if the Wemma wedding does fall through, some other "Glee" couples may be reconciling on Thursday's show. As Hollywood Life notes, Murphy has tweeted a photo of exes Kurt (Chris Colfer) and Blaine (Darren Criss) in suits, making it appear that they will reunite for the Wemma nuptials. Murphy himself has confirmed this news in a tweet, noting that the two characters will attend the wedding together and even make out in a car by the end of the episode.

Murphy has also tweeted that another couple will be back together by the end of Thursday's "Glee," which one person potentially pregnant. It's unclear if he is referring to the Wemma reunion in this teaser.

Diehard "Glee" fans may spot another familiar face in Thursday's episode. TVLine has printed a photo showing former "Glee Project" contestant Ali Stroker sharing a dance with Artie (Kevin McHale) at the wedding in question. Stroker, who will reportedly play Emma's niece, was a finalist on Season 2 of "Glee Project," losing out to Blake Jenner, who plays Ryder Lynn.

Stroker, who is paralyzed, recently spoke to WetPaint about the idea of Artie dating a fellow wheelchair-bound character.

"I know many people in chairs that when they date, they're not looking for someone else who's in a chair because they're like, 'Oh, it would be very difficult."' Stroker said. "But, no, that's saying that being in a wheelchair is difficult, and I've never felt that way. I feel the experience of being in wheelchairs is exciting and adventurous."
