Watch Slayers Season 3 Episode 18 Online

Amelia and Gourry decide to hang out with 3 old people (and their friends) "fighting in the name of Justice" wanting to slay some demons. In the end, the evil trolls (or dwarfs) are actually good, and the demons that Amelia and Gourry had to slay was Lina, Zelgadis and Filia. Lina and Filia got offended when the 3 old people start to call them demons, and started to yell at them. Then the old people fell over, and Lina tried to wake them up (of course they weren't dead.)
