Hail Il Daniel!
I wonder if anybody here was able to find the secret in the third panel when they first saw this strip. I certainly didn't. Of course, it doesn't really help that Ellen there looks almost exactly like Elliot and the images are so small you can hardly make anything out.
By the way Dan (assuming you read these threads), out of curiosity how long in advance did you have the basic idea for the Sister storyline planned? Was it right from the beginning or did you think of it sometime afterward?
