Vincent is basically the main character of this whole friend group.
Not much is known about Vincent's backstory. Apparently, he's had, like, 800 girlfriends and they were all crazy bitches. Also, his old friend group was edgy as shit and were all Homestuck kin. I know because I talked to one, and she said she killed her guinea pigs and blamed it on her ASPD. What the fuck, Vincent. Also, Joel was there.
