That is why I think that the Thing "saves" DNA from past immitations. That the Thing that "took over" the husky at the Norse camp had previously taken over a man.

Or those of the Palmer or Norris, one of whom had been assimilated by this point. XidiouX

That would be interesting. The "eyes" were blue, does Norris or Palmer have blue eyes?

Knowing this wouldn't enable us to determine which one was assimilated because, like you say, it could have been one of the Norwegians, and we don't know the colours of their eyes. XidiouX

Indeed, a fairly creepy concept lol How many dogs were assimilated during the dogtown scene? I know Macready shot one of them to keep it from being assimilated and another one was taken over I believe. So if this is true, then one of those eyes would have to be either Norris/Palmer.
