Alcyone begs Zagato for another chance, but he reminds her she’s betrayed his trust twice already. She swears she has a plan to defeat the Magic Knights this time and Zagato leaves her to it. The Magic Knights arrive at a lake and wonder if it’s the Spring of Eterna. Mokona shakes its head, but Umi wants to investigate anyway. A boat just happens to be there, so they board it and look around. A monster appears out of the lake and knocks the girls back ashore. Hikaru attacks with her sword, but it doesn’t work because the monster is made of water. Umi uses her Water Dragon spell to destroy it and the water that falls on them makes them glow temporarily. Mokona points the way to Eterna as Alcyone watches on. They finally reach Eterna, only to find that it doesn’t look like a spring at all. They examine a glowing line floating above it and discover it looks like water when seen from above. Umi wonders where to find the escudo and Mokona jumps into the spring. The girls resolve to jump in as well and they find themselves separated. Hikaru senses something approaching her, and to her surprise it’s her dog Hikari. Umi searches for her friends when her parents appear before her. Fuu is confronted by another version of herself.
Hikaru is attacked by Hikari, Umi is attacked by her parents, and Fuu is attacked by her doppelganger. Fuu soon discovers that she and her double receive the same damage. Hikaru tries to talk to Hikari, but it has no effect. Umi can’t bring herself to attack her parents and Fuu notes how much more confident her copy looks. Emeraude appears to the girls and asks them if the ones in front of them are really their loved ones. The Knights say how important their opponents are to them, but Emeraude asks if they would really attack them like that. The girls see her point and they fight back. Hikaru beats Hikari with her Ruby Lightning spell, Umi beats her parents with her Sapphire Whirlwind spell, and Fuu beats her other self with her Emerald Typhoon spell. They find themselves reunited and before them are three stones of escudo. Fuu figures they were being tested and Alcyone appears to say that escudo is only granted to those who pass the test. The Knights suddenly fall to the ground and Alcyone explains that the water monster’s poison is taking effect. Alcyone starts freezing them, but they manage to stand. The escudo goes into the gem on their hands and their armor evolves. Together, they use their new spells to defeat Alcyone. They exit the spring and start heading back to Presea’s place. Alcyone crawls back to Zagato and begs for forgiveness, but he blasts her away. He admits to taking the Magic Knights too lightly and he sends the summoner Ascot after them next.
Our heroes finally make it to the Spring of Eterna, but getting the escudo was no easy task. Being faced with those precious to them made them falter, but thanks to Emeraude’s words they fought back and proved themselves worthy. Alcyone has a pretty decent plan, but she underestimated the Knights’ will power. They gained enough EXP to reach the next level, learned some new spells, got better armor and sent Alcyone packing. Of course, she begs Zagato for yet another chance, but he’s had enough of her incompetence and gets rid of her. This episode had some really good moments and used its time more effectively than the previous episode. Alcyone might be out of the picture now, but Zagato’s got more minions where she came from.
