"Zelgadis-san?" Amelia asked uncertainly, backing up half a step.
Zelgadis stood up, causing Amelia to back up another step. "Listen, Amelia," he said. "I've been this way for years. Rezo, my grandfather, did it to me. I only appeared human because of a deal I made with Xellos, and--"
Xellos butted in just then, grinning, and said, "And since he didn't complete that agreement, he now belongs to me!"
Zelgadis glared at Xellos. "What if I refuse to come with you?"
In response, Xellos grabbed Amelia by her arm, yanking her over to him, and held his staff up across Amelia's neck. Amelia's eyes went wide, and she froze, lest her movement provoke Xellos to hurt her.
"Xellos!" Zelgadis shouted, shocked for Amelia's safety.
"If you don't come with me," Xellos began. "Then she dies." To prove his point, he held his staff closer to Amelia's neck. Amelia tilted her head back to avoid the staff touching her, and looked with fear-filled eyes at Zelgadis.
For a moment, Zelgadis was silent. Then, "All right. I'll go with you if you don't hurt her."
Amelia's eyes went, if possible, even wider. "Zelgadis-san!" she cried. "You can't do that! I-- I'll go instead! But I won't let you sacrifice your life to him just to spare mine!"
Zelgadis shook his head sternly, and said, "No. I made the contract. I'm going with him."
"No you aren't! I won't let you!"
"Yes I am!"
"You're not!"
"I am!"
"You aren't!"
"I am!"
"No! You're not!"
"Yes! I am!"
"No, I won't--"
"ENOUGH!" Xellos shouted, interrupting the childish argument. "Though you were the one who I made the deal with, Zelgadis, I'm afraid the offer of this girl taking your place is too much to pass up. I'm going to have to take her instead." Then Xellos, holding onto Amelia, began to phase away. At the last possible moment before he and Amelia disappeared, Zelgadis grabbed onto the edge of Xellos cape, getting teleported along with them.
(~~~~~~~~~squigglies~~~~~~~~~~)
When Amelia and Xellos appeared again, they were standing on a rock that jutted out over the lake. Xellos left Amelia there, and went to hover over the water. "You're a foolish girl," Xellos told her. "But I'll enjoy killing you."
"Wh-what are you going to do to me?" Amelia asked, more than a little scared, but trying not to show it too much.
Xellos grinned, his violet eyes flashing. "ZELAS GOTO!!!" he shouted, raising his arms high into the air.
Below the hovering mazoku, the lake started to swirl in a giant whirlpool. Things that had once been on the bottom of the lake began to resurface and float in a circle around Xellos. On one of these items, a small rowboat, sat Zelgadis, who had landed in the lake when Xellos had reappeared. Being made of rock, Zelgadis had just sunk, but now that things were emerging and floating, Zelgadis was able to take in the present situation: Xellos casting his spell, and Amelia sitting, terrified, on the rock.
Quickly, Zelgadis looked around for something-- anything --he could use to stop Xellos from casting his spell. Conveniently enough, in the rowboat was a harpoon. Zelgadis took it in both hands, and aimed it at Xellos. "Prepare to die!" he shouted at Xellos.
Xellos looked down to see who had called to him, and saw Zelgadis just in time to have the harpoon shot at him. It went right through his chest and out the other side. Xellos let out a choked gasp, before teleporting away to heal himself.
Of course, once he was gone, the power of his spell died away. Things starts to sink again, along with the rowboat Zelgadis was in. Zelgadis looked over to where Amelia was one last time before he was pulled under the surface of the lake.
Amelia could only watch in horror as all of that unfolded. "Zelgadis-san!" she cried after he'd sank again. "Zelgadis-san!!" She knew there wasn't anything she could do, though. Even if she got down there using a Ray Wing, she'd never be able to get him out again. Sadly, Amelia made herself get up and walk away from the lake and head back to the palace. "I'm sorry I couldn't help, Zelgadis-san..." she muttered quietly. A few lone tears streamed down her cheeks.
