I don't own Glee, or Buffy. This is a crossover. You've been notified.
Dave's not sure what's going on the first time he sees the boy. It's just a glimpse of him in the hallways, and he passes around a corner before Dave can follow him, and by the time he makes it to the corner, there's no sign of the other boy.
The second time Dave thinks of that Star Trek episode where they see alternate versions of themselves. He tries to follow him, but this time Dave loses the other boy halfway through the cafeteria. Something about the guy's jacket irks Dave, as if there is something distinctly wrong about it.
A blazing 'S' on his chest is the giveaway Dave decides the third time, chasing him across the gym floor into the locker room. Once again there is no sign of him when Dave enters. However, the next day when Dave stows his things, the boy comes to him instead.
"Hi, I'm Larry," he says warmly, extending a hand. Karofsky snorts derisively.
"What kind of idiot names his kid Larry?" Dave asks shoving more crap into his overfull locker.
"One did oh, 30 years ago?" Larry says calculating it out. Dave's eyes bug out.
"You're thirty? Are you some kind of pedo?"
"You really should have tried the hand shake numbskull." Larry states. He slaps Dave, only for his hand to pass through Dave's face. "I've been dead for a lot of those years."
"Why are you here?" Dave asks. Why was a ghost haunting him?
"The Powers That Be sent me to make sure you graduate without dying or killing anyone. In a sleepy town like this, it shouldn't be that tough." Larry explained.
"Why you?"
"Because I know your struggle and because I died at graduation." Dave opened his mouth to ask another question but was cut off by Larry holding up a hand. "Someone's coming. See you around Dave." He blinked, and Larry was gone.
Dave was seriously concerned. A ghost? Was he going crazy, or was there really a ghost looking out for him now? After had gotten home, and locked his door to his room, Larry came out again. Larry looked around the room, at the posters taped up on the walls. Several hockey teams were plastered on the walls. "Well, at least it's not bikini chicks, but I think you had some questions for me." Larry says appearing to sit on Dave's bed.
"How did you die? What do you mean you know my struggle?" Dave asks. "Where are you from? Why—" Larry holds his hand up to slow the questions down.
"I died at graduation defending everyone from the mayor who had decided to become a demon." Larry shushed a disruptive Dave. "Still my turn. I'm gay Dave. I was a bully, and when one of the kids I trashed confronted me in the locker room, I caved. I let it out to Xa—him, and he didn't make fun of me. So I told I everyone. I was so out, my Grandma Betty was setting me up with guys. As for where I was from, there was this little place called Sunnydale, California. It collapsed, going on eight years back? Turned into a crater. So you've got some out of me, do you have anything to get off your chest? I'm not going to judge you, just listen."
So Dave told him everything. The first time he saw Hummel. The first time he had one of those dreams about him. Then the name calling, the locker shoves, and… the 'incident'. He couldn't get himself to say what had happened there. "Dave, I'm dead. Who am I going to tell?" Larry asked. With those words, Dave felt his walls crumble.
"He was so beautiful, and so angry with me. We both said things that were unkind, but he wouldn't go away. He kept shouting in my face and I – kissed him, and it felt like heaven. I stopped, just to see what he looked like, and he was so confused. So I leaned back in, but he shoved me! It hurt so badly, and I could feel myself tearing up. I had to get out of there so he wouldn't see me crying. I left, and found the astronomy room. No one's in there except for hookups, so I just let it out. I was going to never mention it again, but that idiot, and his new best buddy tried outing me in the staircase. I… threatened him, and he eventually transferred schools."
"You know Dave, you really stepped in it." Larry told him.
Dave knew it was true.
