TBTB probably didn't think about this as they just threw the travelers in as a limo service more or less but the Pegasus Asgard and the travelers both seem to have alot in common. Both their societies are in hiding from the wraith and both seem to be experts at surviving, doing whatever it takes to survive. They are both in essence lost tribes. I thought it was really neat having them in the same episode and even fighting each other as they are essentially in the same boat and don't even know it. A pity the show is ending as it would have been an interesting twist to see the Travelers and Pegasus Asgard form an alliance in the future to destroy the Wraith and have Atalntis caught in the cross fire.
