He knew he was being slightly ridiculous. After all he was the glee club's advisor and the only faculty member, sans Brad, who actually had the key to the April Rhodes Civic Auditorium. So he didn't really have to sneak into the back of the auditorium to try to figure out what two of his students were up to. All Will really had to do was just tell them the stage wasn't available for some vaguely plausible reason and force them to use the choir room for their extra practices.

He did want to be surprised when the kids performed in a few weeks, but that wasn't to say he wasn't intensely curious about what exactly was going on with each duo. Will figured Artie and Puck were probably learning towards something guitar driven given both boys talent in that area. Hopefully Finn and Brittany would find something that combined his singing and her dancing. If Mike and Mercedes stopped pretending they weren't interested in each other for longer than five seconds, he was confident they would probably blow everyone away. Will knew that like all teenagers, his students thought he was completely blind but there was no way he could miss the looks between the two of them. Santana and Rachel? It was a pairing he almost wished he had thought up. Rachel would realize there was more competition than just Mercedes and Kurt for her solos and Santana really only responded to direct competition. The fiery cheerleader would try that much harder in their every routine. With Quinn and Tina it was a tossup. Either Tina would end up giving Quinn a Goth make over and the two would rock out or Quinn would prevail and the two would harmonize beautifully.

The wild card in everything was Matt and Kurt. Try as he might, Will could not come up with one idea what the two of them would end up doing. They were so different style-wise when it came to music. Matt had auditioned with a Michael Jackson piece, emphasizing his dancing over his singing. Kurt had sung Mr. Cellophane with an attitude that dared Will to find anything wrong with his performance. Matt appeared to be perfectly happy to never have a solo while Kurt had gone and joined the Cheerios to get his chance in the sun. While Will couldn't imagine Matt ever considering singing a girl's part for competition, Kurt wouldn't think twice of it. And although Kurt was turning into a good dancer, he wasn't near Matt in terms of ability.

Plus, Will couldn't deny he was curious about the recent closeness that sprung up between his quietest member and one of his most outspoken. He had always had to correct Kurt and Mercedes to pay attention during rehearsals instead of giggling over whatever had their attention, but he was starting to have to shoot looks in Matt and Kurt's direction as well. True they weren't disruptive but he had noticed the two of them making faces and passing notes to each other through out their meetings.

So when Matt had shuffled up after Spanish class and asked to use the auditorium after glee today, Will not only agreed but planned on sneaking in to attempt to get some idea of what exactly was going on with these two.

He took a seat in the furthest back row, seeing Matt and Kurt sitting on the stage with music sheets and CDs spread between them. From experience he knew that if he stayed quiet, neither boy would actually see him with the stage lights being lit.

"Ok we have to focus." Matt picked up a CD and tossed it towards Kurt. "No more getting distracted. We have to pick a song today."

"You say that like it's my fault we haven't accomplished this yet." Kurt took the CD and glanced at the cover quickly before putting it back on the floor. "That's a definite no."

"You're a snob." Matt countered quickly but still handed over another CD. From the way he said, Will had the feeling this was well covered territory between the two. "And it is your fault. You get all caught up in your failed career as a matchmaker and we ended up working on that or I trounce you in movie war."

"Excuse me? I am not a failure as a matchmaker. Mike and Mercedes are stubborn that's all. And the official score of movie war is a tie."

"In your dreams it's a tie."

It was utterly fascinating to watch as they picked up and discarded CDs and sheet music with barely any discussion. Every decision seemed to be made through a series of facial grimaces and raised eyebrows. Will was sure neither one was fully aware of what they were doing but it was as if he was watching a well-established musical act deciding a set list. Hands flew and brushed past each other without a second thought. Everything was settled by the eyes.

"I thought we were in agreement that Mike and Mercedes were too stubborn for their own good and needed a little nudge." Kurt held up the CD and shot Matt a scathing look. "You better not even be in the same league as serious with this one."

"I thought you liked musicals. Avenue Q is a Tony award winner."

"Yes but If You Were Gay? Come on; does anyone really wonder about that anymore?"

"Ok fine I was joking." Matt sighed and rolled his eyes. "And there is a difference between nudging and what you've been doing. "

"You're just saying that because you know that once I get those two together, you are next on my list Rutherford. There is really no reason for you to be single. "

"Yeah. Not happening." Will puzzled over the small change in Matt's tone when he rushed that statement out. Kurt was too involved in reading the back cover of a CD to actually notice but Matt looked away and at the stage floor when he said that. That was….interesting.

"You protest too much. You will see I will find you the perfect girl for you. Just you watch."

"Considering the way Rachel stalked you, a sane person would be anti-matchmaking."

"Yes but that was Rachel and in the end I got Sam. So the good outweighs the bad there."

It was brief and if he was sitting closer, Will would have been better able to see the flash of emotion that crossed Matt's face. But to do that, he'd have to alert both of them to his presence.

"Yeah I guess that's right." Will had to strain to hear Matt's soft voice.

"Hold it. May Larson's ghost strike me down if I'm lying but I think I've found it!" Kurt scooted closer to Matt and put the CD in his hand. "This. The first song. It's perfect. Completely in your wheelhouse."

Matt puzzled over the song Kurt was excitedly pointing to. Kurt was practically jumping on top of Matt he was so excited. "Adam Pascal? Who is he?" Matt asked.

"Who is Adam Pascal?" Kurt's outrage didn't need a single microphone to be expressed. Will was quite sure Terri had just heard that in the stockroom at Sheets-N-Things. "I seriously need to educate you. He was the original Roger in Rent. "

Seeing the blank look on Matt's face, Kurt threw up his hands and stood up. "Oh screw the way we drew cards. Rent is the next movie."

"I've never heard of this song." Matt followed Kurt's lead and stood up. "Brad's not going to know it."

"It's just a piano and guitar." Kurt argued. "I saw the guitar in your room so I know you at least know how to play a little."

"Well yeah but…."

"And I play piano. This makes it perfect for the whole surprise element Mr. Schue was looking for."

"I thought you said that was me singing lead."

"That too." Kurt waved off Matt's comment before grabbing the other boy's hand and dragging him over to the sound system. "Look the words are in the booklet. So that part's taken care of. The hard part is going to be figuring out the melody and harmony lines for the instruments."

Silently Will stood up and slipped out the heavy double doors. Matt singing lead certainly would be unexpected. But Will suspected the bigger surprise would be when it became painfully clear Matt was nursing one hell of a crush on Kurt.
