Well, Luna figured it out, did a little cat flip thing, and caused a wand to appear. This wand would then be used by Ami to call upon the powers of Mercury. So what are the powers of Mercury? Well, um it's like the Mercury Bubbles, and all that, and although this may be the weakest powers of all the scouts, Ami's bubbles have often been used as a fog which partially blind the enemy. Oooh, and later on she gets this little visor thing which comes over her eyes which allows her to play with this computer thing. She usually uses it to figure out things about the enemy. Weeknesses and all. It's like this clear blue visor thing.
So anyway Ami turnes out to be one of the good guys, Ami and Serena destroy the evil people, the class is returned to normal, and they all live happily ever after.
I can't think of anything else to say about Ami, so just look at the pictures and enjoy.
