I adore Cam, don't get me wrong, but he and Jack are very different. I mean, SG-1 before and after Jack are actually really different shows, in a lot of ways, so maybe if you look at it as a different series?

Plus this means you know nothing about Janet Fraiser except from her bits in Ripple Effect, and Janet is awesome enough that everyone should get to know who she is. (Carolyn Lam also rocks my world, mind you, but in a different way.)
