Yeah, I should have done it that way in the first place. The gag being, of course, that they all more or less look the same.
I tried to have a same-but-slightly-different look at the beginning, and that just prompted readers to try and guess who the coffee-shop guy was.
So I changed it so the gag was a bit more obvious.
And I've been thinking I shouled add them to the cast page. Same thing, all the same picture, nearly identical descriptions... Maybe a 'Favorite phrase' of "Resistance is futile, you will be assimilated"...
