I think it could have wound up a lot more interesting with the memory charm lifted once the Oracle was dead.
For instance, Haley leaves Belkar. The Linear Guild comes to see the Oracle and find a dead Oracle and a sick Belkar. Recognizing an opportunity to recruit a semi-competent evil character with inside information on the Order, Nale takes Belkar to get him cured of the MoJ. From there, any number of things could happen. Traitor, double traitor (once Belkar sees Roy alive he falters and lets the Order get away again, or remembering what happened when Belkar's wisdom score went up, someone hits him with a maximized Owl's Wisdom and he's temporarily good, etc.)
Or Haley leaves Belkar. Belkar wanders off on his own for a while, then collapses on the road. Team Evil is marching towards the next gate and comes across a nearly dead Belkar. The Monster in the Dark recognizes him, and Xykon keeps Belkar alive to amuse himself and/or get more information from Belkar, convinced he must know more about the gates than they do. Eventually to be rescued but costing the Order another victory.
Or.... Well, any number of things.
Enforcing the memory charm now is sort of anti-plot. It stops a great number of possible things from happening.
As it stands, that was six and a half strips and a little over two weeks spent entirely on getting Belkar's Mark of Justice activated, and no one even remembering it, and that's about it.
