Is it weird that I have the occasional dream (like last night) where Cass either is made Batgirl again or has her time as Batgirl restored?
No, no it isn't weird. Just a look at what reality should look like.
Semi-related note, but for some reason the dream reminded me of the poll which was going on when I came to the forum about which Batgirl had the best look. For some reason I voted for Steph as I recall, and I can only blame the meds I was on.
