It’s not the first time you’ve been there, but whenever Dave asks you if you want to “go to his lab”, you can’t help but laugh and suggest that he’s secretly some sort of evil scientist that’s going to experiment on you.
Obviously, he isn’t, but it’s still fun to tease.
His lab isn’t a lab in the traditional sense—it’s an abandoned subway turnaround, probably from the thirties or forties, that he’s crafted into something of a makeshift workshop. He works a lot with electricity, so the school gave him this space to work on his thesis project.
You just like hanging out with him there, because you can sit prettily while he works.
After making it down the numerous flights of stairs and into the honestly beautiful underground space, you settle into one of his favorite rolling chairs—not that he minds, really—and watch him as he sets his things down and immediately heads off into the space.
