Well Sheryl did get a chance to pilot the Blue VF-25 and that didn't turn out so well. I don't think she's gonna be piloting anything. She's in the same school, but not in SMS. I think she remembered her calling in this episode and is gonna go back to singing for the people. As for her slapping Ranka, it was a get a grip girl slap. A Minmay Slap. Hikaru did it to Minmay to shock her into listening. Too bad it didn't work to well with Ranka, but she did stop bawling and heard what Sheryl had to say to her. Remember it was Sheryl that encouraged Ranka to follow her desire to sing. I kinda saw Sheryl as Ranka's big sister/mentor even? Yeah she got jealous, but seriously who wouldn't after all the spotlights and your own manager shifted away from you to this girl you pushed forward into the light.
As much as I keep toying with the idea of Mikhail being saved, i do believe he's toast. Seeing the previews of the next episode makes me think that somehow the tide turns against the Vajra, the Cayeenes are cleaning house with the flame throwers (Aliens on a huge scale) and man....see that body count? People are mourning, mini-KK (post fight) needs alone time in Mikhail's fighter so she doesn't bite it in the next episode. I think those raging eyes of hers will occur early in the episode after she finish macronizing (is that even a word?).
You know I was just thinking Mikhail was a womanizer like Roy. Yes Roy was loyal to Claudia (sorry to use the RT name), but he was caught looking at Minmay's butt in SDFM. And they both kinda declared their love to their true love (Roy to Claudia (indirectly) and Mikhail to KK directly although he got cut off at the end of his I Love You declaration by the vacuum). His death scene was perfect, fight, life flashing before his eyes, declaration of love, and only a momento of him left. What great direction and voice acting. Speaking of voice acting...Man...can you hear the english voice dubbs? *Cringe* So yeah Mikhail's dead....sigh...I think I need a few days for greiving....
