Firstly, MERRY CHRISTMAS! Also, HAPPY HOLIDAYS! And who can forget, JUBILANT MONDAY!
Got ALL the bases covered.
Just making sure
Friends don't let friends do things while under the influence of secret identity form-type magic without checking to make sure they'll be cool with it later.
That's not being a wet blanket. That's being a cool friend. Now please magine a rainbow star with piano music.
I was about to write the specifics of what Susan likes and doesn't like about the form, BUT NO
THAT IS NOT MY PLACE.
INTERPRET HOW YOU WISH.
THAT IS YOUR POWER.
Granted, she might elaborate herself eventually points that would explain it, but that's the comic's job. My job down here is writing vaguely amusing nonsense that may or may not be interesting in some way.
