I'm going back and watching the first season. If you go back and look at Leonard in "Numbers" And Radsinsky in "Namaste" they look like the same person. And the glasses they are wearing look exactly the same. Has anyone else thought this? Could that be why Leonard keeps repeating the numbers? He is the one that worked on the Swan. They just look too much alike for this to be a coincidence. Check out the episodes and tell me what you think.
