Thoughts on Ripple Effect

Ripple Effect was in syndication today. And for some reason, I find it hard to believe that, even as close as the universes are, that everyone looks exactly the same. Sam's hair is always the same length and the same shade of blonde. Daniel has the same glasses. Etc etc. I know it's a silly thing to obsess over, but it's kind of one of those things where if someone had thought about (wait? Stargate writers think?), it would have made the episode that much better. You know?
