Emma's graduated but I can't find her

Hi, all!

Emma has graduated from school and I thought I would find her back at school so that I could recruit her but she's not there. I checked the walkthru & know where she should be, but no luck!

I'm at the end of the game going to fight the Snow Queen and the walkthru suggests to have Emma in the party & I had forgotten about her, so now I'm looking for her.and she's nowhere to be found. I looked at the school and at the tournament and still no Emma. Am I screwed for finding her?

Any ideas, suggestions would be greatly appreciated! Thanks in advance.
