Here's just the inks and gray shading. I'll have to add color later.
I wanted Grace to have a crush on Annie. I think just that it seemed funny with the person that Annie can't understand. Grace is a pervert, but I wanted to give her a more common setup here. Kind of convert her initial curiosity to something else.
I doubt Grace makes the connection that this is the same person as before yet. I thought she'd run away because she's really kind of cowardly about her emotions. She's probably stealing underwear as an outlet for her attraction to other women, but she's not brave enough to talk to one that she's interested in.
EDIT: added color and made a number of minor changes.
