/ UPDATE: Michael Ausiello of TVLine spoils that one of these two characters in question is Tina. Who is the one she'll be making out with? Well, Ausiello hints that it's looking like it could be this scene in season 5 episode 10, "Trio" (see photo right). So...is it Chord Overstreet's Sam?

Remember when those two characters on Glee had the grossest make-out session ever, and everybody was like, "Ewwwww!" Well that's because it hasn't happened yet.

Check out this spoiler from TVLine:

...BONUS SCOOP: Two characters with no shared romantic history whatsoever will do the tonsil tango this spring (and their PDA will be met with a resounding, “Ewwwww.”)

How gross does this "tonsil tango" have to be for the ones on the show to go ew? Who do you think it is? Any guesses?
