After the debacle with the White Mage, all of the Fairy Tail Guild members felt remorseful for their actions while they were brainwashed. One of course, was Mirajane. She felt awful for leading Lucy and the others into a trap so The White Mage could drain their magic. Not only that, but also attacking Lucy with Elfman and Lisanna.
Mirajane stood behind the bar when she saw Lucy enter the guild. Mirajane was currently wearing her usual pink and red dress and a pair of matching red heeled sandals.
Mirajane: walks over to Lucy, guilt still on her face Lucy, is it alright if we talk?
The two sit at a table
Mirajane: I would like to sincerely apologize for my actions while under The White Mage's control. I feel simply awful about leading you and the others into a trap and even going as far as to attack you with my siblings… she says, hanging her head in shame
Mirajane: I just hope that you can find it in your heart to forgive me and we can still… be… friends…? Mirajane looks up as she could hear Lucy holding back giggles
Mirajane: pouts Lucy, I'm trying to apologize for what I did while brainwashed, now's not the time for giggling at me…!
