In Michael Ausiello's March 5 "Ask Ausiello" column for TVLine, he spoiled that Will (Matthew Morrison) does find out about Cory Monteith's Finn planting a big one on Jayma Mays' Emma right before the almost-wedding.
Bonus Scoop: Finn tells Will that he smooched Emma, and Mr. Schue responds… quietly.
Responding "quietly" sure can't be good. Do you think the Schuester will eventually blow up about it?
While we don't know when or how the truth will come out, think it's pretty safe to say that Finn just won't be able to take the guilt anymore. Unless maybe Emma comes clean...or do you think Will finds out in a roundabout way?
