Remember, the expected HP loss from the ritual is less if Arjhan and Zimelda "aid another" in the heal check for the ritual (and of course Zimelda can heal the HP back more effectively than you just burning surges). Zimelda wasn't with the group at the temple. So if you want just Arjhan to help, we can retcon it (in fastforward if you want). If you want Zimelda to help also, you'll have to RP making peace with her and then going back to the temple.
