Well I suppose there are times when Alan's "I'm not going to bother unless you start the fight" attitude can be entertaining. He realized what was up but didn't want to bother fighting if it wasn't necessary. Though I think he should take the Frieren approach and just presume the demons are all evil unless proven differently
.
Everything was resolved fairly quickly once he did take action. The most silly part of it was the necromancer figuring he had some shot to win against Alan despite him instantly breaking his spell controlling Lise's Uncle.
Again the show is pretty cheap and not that deep. But there are little things that are alright. The Uncle just confirming that Alan would both protect and be able to protect Lise was nice. And even sporting the guy one last sparing match before he died for good. I'm ok with that.
