A common terminology for the player groups is A1 for Meenah's trolls, A2 for Karkat's trolls, B1 for John's humans, and B2 for Roxy's humans. IIRC this was coined by Aranea in her dreamchat with Terezi, although B1/B2 was foreshadowed much earlier.

Oh yeah. I forgot to mention that earlier. Thank ya kindly.
