Whose session is the b1 one? Whose session is the b2 one? Whose session is the a1 one? Whose session is the a2 one? Sorry, the those names for the sessions confuse me •~• oh and by which name of that similarity would Caliborn's be??? Thanks.

The A1 session was Meenah’s, the A2 session was Karkat’s, the B1 session was John’s, and the B2 session is Roxy’s. Caliborn’s session would presumably be C1 going by the pattern.
