Well, I hope you give it a shot though. It's definitely an underappreciated pair.I know >__< It really made me want to write a fic where he leaves the shop to come back to them. Which I might do but I'll probably be all 'durrrr~~' through it because I've never done anything for Slayers before. :/ I think Palu's mom name was Elena too, but I'm not very sure because I don't remember them saying it in the episode.
I don't remember her name coming up, but it could be.
EDIT: Yeah, Kanzakadex says you're right. It is Elena.
XD Well, it's pretty clear how I feel about Xellos/Filia. I gotta admit though, Jillas/Filia is cute from a one-sided perspective. It's kinda amazing to look back on the anime and see how EARLY his crush on her started. Pretty much from episode 5 on "Gotta take care of the 'ostage!" :P...And that just made it even more likely in my mind. XD As much as I like Filia/Jillas, her with Xellos has, uhhh, more canon-potential? (or it would be easier to get them together)
I STILL am upset that the ending with Filia, Jillas, and Gravos at there shop didn't have some kinda touch like Xellos at the window or something. I realize that they wanted a shot of him reporting to Zelas and they couldn't really have both, but STILL.
XD You know, that's kind of how I feel about the movie. I know it's not *good* but I still like it anyway. I have my Slayers biases donchaknow. At least it actually had the main cast unlike the other OVAs which just had Lina and Naga. AND Slayers Premium actually had some fun shipping moments. I particularly liked the ones between Zelgadis and Amelia. And of course, I also like that OVA because it implies that Zelgadis and Amelia traveled alone together away from Lina and Gourry. Hello shipping potential!lol, I remember only seeing the movie of that. I thought it was stupid but I liked it anyway. o__0 There were some funny parts there.
...Although I will say that Amelia got a bit of a raw deal at the end of the movie (though that did facilitate an AWESOME Zelgadis reaction). It looks like that's not the case in the manga though I've glanced over it for scanning so far and haven't read it.
