The next episode of Glee will be explosive!

Last night's Glee -- "Mash-Up" -- was one of the best of the season, but it may be that it was merely an appetizer and that next week's show is going to be the big enchilada (hmm... I must be hungry). Anyway, the show won't be back until November -- after the World Series --- and based on Fox's previews, it looks like a lot is going to happen.

Just from the previews alone, we know that the truth about Quinn's baby is coming out. Puck lets it out that he's the baby daddy, not Finn. And he tells Mercedes, which means the entire New Directions crew is going to hear about it... not that Mercedes is any more a big mouth than the other glee kids. But this is high school and these kids like to blab.

On the musical front, Kurt's going to go nose to nose with Finn in song. And not a hip-hop, finger-snapping dance tune. Nope. It's ballad time. As Kurt said in the preview, it's time to "sing to me everything you feel."

Finn has trouble expressing his feelings to Quinn and Rachel, how do you think he'll do with Kurt?

In other action -- and these probably qualify as spoilers, so stop reading unless you want to know --

...there will finally be some story line for Artie. The episode is called "Wheels" and Will is going to ask the kids to learn what it's like to be in a wheelchair by performing in the chair. Sue sabotages Will's plans for sectionals. And Rachel's ruthless in her attempts to get a big solo.
