Zelgadis is given a chance to turn human, while still keeping his chimera form. Can he control the change, or does something have to trigger it? Does he tell his companions about it, or does he hide it because it's not a full cure? Does he even take the chance, or does he refuse, because he wants that elusive full cure?

Sorceresses lose their magical powers once a month for... erm, delicate reasons. Guys don't have "that time of the month"... as far as we know... or do they? Is there any time that a guy would naturally lose their powers for a limited amount of time? (This does not include spells that take away powers.)

Lina's scary big sister, Luna, tracks Lina down for some reason. What is that reason? Is Luna able to calm Lina down long enough to explain what the reason is? Does Luna have to travel with Lina, until whatever needs to be done is done?

What happened in any of the character’s pasts?
Lina’s deathly afraid of her sister, Luna. Why? Does she have any other siblings? What about her parents? Why did she leave home?
Was Gourry always that forgetful? Who are his parents and siblings? Why did he strike out on his own? How is Rowdy related to Gourry? (Rowdy is from “Slayers: the Motion Picture.”)
Zelgadis never talks about his family, or his past. Do they even know that he was turned into a chimera? Is his family rich, poor, royalty, peasants? Why was he so obsessed with becoming strong? Was he an orphan?
What was Xellos’s upbringing like? Was he born a mazoku, or did he have a human life? Who helped teach him in the early days?

Zelgadis gets the cure to his chimera state. Now what? Would the magical powers he enjoys as a chimera be the same as a human, or would he lose that ability? How strong would he be as a human? Would he really be satisfied as a human, now that he’s been super strong, super fast, and a very powerful sorerer? Could he really give all that up? Is there someother reason he wants to become human again? Was there something he lost that was very important to him when he was turned into a chimera? Would he be strong enough to survive Lina’s company as a mere human? Could he now admit his love to another character?

Zelgadis hates Rezo for turning him into a chimera. What if there was another reason, too? What would this reason be, and why hasn't he ever told anyone?
