McKay: (When they learn that this Beckett is a clone) It doesn't matter.
Beckett: Well, that's easy for you to say, but you're not the one who just found out he was made in test tube.
McKay: As far as I'm concerned, one of the best friends I ever had just came back from the dead. I'm not gonna quibble over a couple of telomeres!
Beckett: Well, thank you kindly for that, but it still doesn't change the fact that I'm not the real Carson Beckett.
McKay: No. No, you're not, because the real Carson Beckett wouldn't be standing here feeling sorry for himself. He'd be trying to figure out how to help us.
