Oh, I like this! Their casual acceptance of visitors from other universes is great, and so is Lorne's careful, only slightly bemused reaction to the whole situation (which, I suppose, is what years of working with the SGC will do to you). And I like the little differences between the universes, and Lorne's concern over some of them, and how careful he is when talking about the reasons for some of the differences in his universe. This is great!
