The winter finale of 'Glee' looks like an appropriately intense one. Episode 14, 'On My Way,' is full of revelations, surprises and obstacles that will absolutely make it a must-see event.In the new promo for the episode, the Troubletones perform Kelly Clarkson's 'Stronger (What Doesn't Kill You).' Since the music reflects the themes within each episode, we're guessing there's going to be a lot of adversity to overcome in this one.

'Plans change,' the screen reads just as Rachel (Lea Michele) reveals to Finn (Cory Monteith) in the hallway that she wants to get married immediately. 'People change' flashes across the video as Coach Sue Sylvester (Jane Lynch) reveals to Will (Matthew Morrison) that she's pregnant, but we don't know for sure who the dad is. Then comes the biggie: 'Everything changes.'

Quinn (Dianna Agron) tells Rachel -- as the future Mrs. Hudson is trying on wedding gowns -- that she's not going to let Rachel ruin her life by marrying Finn. Ouch! However, Quinn isn't alone with her objections to the nuptials.  One of Rachel's dads, Hiram Berry, who whispers, "We have to stop that wedding." But will they have time? There's footage of her in a gown and veil!

All this and regionals. Blaine (Darren Criss) came back in episode 13, and here he duets with a gentleman onstage. Is it Kurt (Chris Colfer)? All these questions are going to eat away at our brains until Tuesday! Check out the promo below and let us know your predictions.
