Your plan to investigate who these ghosts were had appeared to be a good plan. Unfortunately you had forgotten you lived in Sunnydale. Each grade tended to hemorrhage a good fifty percent of the students before graduating. Picking through who of the many deaths this ghost could be was more difficult than it should have been, and you were honestly regretting this a little.
Luckily you were not part of the research team! You were part of the snacks and morale team, along with Oz and Cordelia. You weren't really that sold on Cordelia actually boosting morale and not just trying to pester them into somehow researching faster, but it was a token offer of support. She had made it clear that she wasn't going to let this ghost business ruin the dance.
"It's not supposed to go this way you know," you were told.
"What do you mean?"
"You took out a pretty big chunk of the tapestry when you offed Angel." She held out the tapestry she'd been working on. There was so much going on, it felt like your head was swimming looking at it. "I have to completely redo this part."
"Sorry?"
"Are you?" She hummed and poked at the edges. "I'm getting to use some new colors. That's nice."
"How does that help find who the ghost is?" you asked.
"Xander?" Cordelia asked. You glanced over. "Yeah?"
"Who are you talking to?"
"It's-" You didn't know. You couldn't really remember what the conversation was about either, besides that it wasn't very helpful. "Uh, think they've got anything yet?"
"Hope so. If this town ruins one more dance-" An arm suddenly reached out of a locker grabbing Cordelia and pulling her towards it. You leaped forward as Cordelia screamed and hit at it with her bag. Buffy rushed up and broke the arm, only for it to dissolve into nothing. Cordelia panted clinging tightly to you.
"This ghost really isn't happy," Buffy remarked.
"You think?" Cordelia snapped.
You met back in the library. At least the deaths had been narrowed down to just those that had happened in February and inside the school itself. You were getting closer to figuring it out, though the list of deaths was deeply depressing to look through.
"I think I found it," Willow announced excitedly. "Look: in 1955 a teacher was shot on the eve of the Sadie Hawkins dance by a student! It's the only death we've looked at so far that's included a gun like the one that's been popping up in these possessions."
"But why would the teacher be shooting others?" Buffy asked.
"I don't think it is," Willow said. "The guy who killed her offed himself the same evening."
"So the guy is just reliving killing his teacher over and over?" you asked.
"Lame," Cordelia scoffed.
"It does give us a method for going forward," Ms Calendar said calmly. "Now that we know the spirits, we can put them to rest much more easily."
