I'm sorry if this seems like an obvious question, but did any of the beta, alpha (kids) and trolls ever meet up in real life before SBURB/SGRUB ever happened? Like Roxy and Dirk meeting IRL, or even Dave and John? Thanks!!

None of the kids did before the game but plenty of the trolls did. Vriska and Equius were neighbors. Eridan and Feferi were together a lot. Sollux had visited Aradia before. Eridan and Vriska used to flarp together. Vriska, Terezi, Aradia and Tavros all flarped together.
