I half agree with Woas. Haley getting hit with non-core spell was an event. Haley actualy solving the problem will be another event. This strip was basically describing how she was in trouble. We already knew she was in trouble, so re-establishing that is not integral to the plot in any way. So this strip is just a filler strip. Now, it's pretty darn good filler, and I did enjoy it, but it's still filler.
Its fun to see how this strip has evolved as a while. Just go back to oos # 1; it looks to very simple and basic, from the art to the dialogue to the humor. And yet, that too had its own charm (we all know this was supposed to be a simple strip in dungeons, before its popularity made rich make it into a uber campaign that...appears to be spiraling out of control)
