I actually did flip a coin, Alexus, because Aaron was with technically with neither group before. But can't really do much, now. I'll keep the current token, Mae.
Also, could these tunnels theoretically go on indefinitely? Since we need a total of 2 clue tokens, and if that were to not happen for quite a while... well, it also slightly peeves me that I don't know what's in the tunnel branching off from Room C, even though it's so close to the entrance.
