Haha. I had two characters with the same bday? Oops! That's what I get for reusing the same couple of dates so I don't forget.
That said, Marlene will show for the DE attacks on Hogsmeade, for sure. Emmeline probably won't go for the attacks since she'll be at work and unable to escape, but she will definitely help out regarding the recovery efforts.
Aaand uhm. The only pure character I have right now is Ariadne, but that would have to be okayed by Faith, too!
