The Last Rune-God: Rayearth, the Lord of Fire - S1.E18

Alcyone spies on Zagato, as he talks with Emeraude. She notices again, he is not physically attacking her, but merely just verbally making trouble. She slolwy gets more of her doubts with the ""kidnapping"" of Princess Emeraude.

Mokona leads the girls into a hot (asui!) volcano where the last Machine is being held for Hikaru. Umi and Fuu starts to get worried about Hiakru when she acts weird, and is disappears (like the others did.)

When this is all happening, Zagato manages to also get to the Volcano when Hikaru just went in. He strips Umi and Fuu's powers, just intime when Hikaru gets back.

Hikaru and Zagato talk for a bit, and he takes her power also. They talk for a bit, for a little more, and he fires a fireball towards Umi and Fuu.
