Go with Jellal and pretend to be Ultear

"I am now Ultear Milkovich, I was a member of the magic council and a member of a dark guild but I'm no longer that person."

says Erza, trying to sum up what she knows about her new body. "I use ancient time magic and ice make magic and..."

that's all she knew about her host body... "not a lot to go with., but I'll manage", says 'Ultear', "but I need to learn how to use my new magic...". she goes back to the mirror and start looking at her new body. she didn't look bad in tights, "they suit me nicely, I think I'll manage to pass as Ultear for the time being" she says, trying to control her new voice.

she heard Jellal from outside "Ultear, are you ready?"

"yes, I'm coming!" says Erza in her new voice, walking out of the room trying to make her best Ultear Imitation while talking and walking.

Jellal and 'Ultear' when out of the inn, and when to their mission.
