Yes. But it's not possible with just raise relationship score with her.
then how do you do it?
You must complete one of the quests, alloving you to kinda "metamorph" too.
so what are the conditions, ie gender, transfiguration being good or D.A.D.A or do I have to do a certain quest before hand
You need to complete the quest with enlarging your wand - then she will ask you "how you doin" ;)
