There's always a reason something goes the way it does... What I was going to say... and got lost when I hit the publish button... Alex Collier just said more simply.... Most of what Alex says I agree with. He's been on their ships in body, with what he says is a frequency belt device. I have not been on their ships to my knowledge. Although there was a very strange inter-dimensional moment in the hospital last year that I don't have a very good explanation for.
Alex is legit, he talks to a different group of Andromedans (the blue ones) than I do (as far as I know Thor isn't blue - but it doesn't really matter, its a big galaxy). Alex's contacts are cousins to the Lakota and Sioux tribes from what I understand.
Thor came from the Celtic diaspora to Andromeda that came out of Atlantis 1.
