Okay three points I suddenly started thinking about for no apperent reason: 1: We know that the wraith can "feed" upon humans because we're they're major food source. We know they inject an enzyme to prevent a human from dying instantly when fed upon, the question is, what effect would they have on any alien race we've encountered, for instance the Jaffa, technically they developed from humans with symbiotes implanted, boosting their ability to combat infections and destroy foreign bodies in the immune system. Would the wraith have any success feeding or not? Same goes for the Asgard, particularly little Hermiod, what would happen in that case would we get aging Asgard or nothing in particular? 2: With regards to linking the two together, we know that ascended beings are aware of whats going on in Pegasus, in Threads (08-18 ) the newspaper that ascended Daniel reads has a headline "Wraith approaching Atlantis", we also know that the Ori we're originally Ancients, and therefore have knowledge of Atlantis and the Pegasus galaxy, we know they can establish stable wormholes to another galaxy, so the question is will we start seeing Priors on the worlds of Pegasus saying "Haloed are the Ori!" ? 3: We know that the Dakara superweapon wiped out all the replicators in our Galaxy, but the replicators were rapidly spreading and didn't care about galactic distances, whats the betting we see a replicator ship that was travelling to pegasus at sometime in the future (think adding the Borg to Star Trek Enterprise)?
