Mostly the same STORY LINE . The other's did leave Tess aka Chris behind, Nesado takes her, tries to condition her into the perfect weapon by using his powers to alter her mind so that she can complete the mission of returning home at all cost, including killing. Which is what I think he did with the actual Tess in the show, but instead of succeeding he failed because Tess/Chris was to strong and escaped. Nesado having lost his perfect weapon goes in search of another, Ava, the New York dupe who becomes Tess as she is known in the show. But because Tess/Chris is the real soul reincarnation of Queen Ava and Max true soulmate, feels it when Max heals Liz and accidentally taps into Liz's doormat seer power and sees the future that happens in the show with, the betrayal and Tess/Ava dyeing ect ect. Except instead of Max and co living happily ever after, Liz losses control over her seer powers and eventually goes insane and Max is not able to help her as his spent his entire life ignoring who he really is. Chris also sees the death and torture of Max son, Zan, who the FBI go after, when Max escapes, because though Zan is completely human, like Liz, his powers developed at the age of 13 the most emotinal age of a teenager. He aceddently exposes himself because he is unaware of his true identity or capability's ( I add this as I don't approve of Max giving him up, because raising him would have been to hard or whatever. Personally I think he did it because of Liz and I think that was not right when Tess gave her very life to protect him). Anyway because she sees the death and destruction that would follow on earth with the skins take over she decides to stop running and go to Roswell to help them.

1. The Call Of A Soul-mate.

Prologe

Chris had felt it the second her soul's, other half, had healed the human changing her forever. Their connection pulled her in and allowed her to tap into the girls future powers. It also showed her a glimpse of Nasedo and her double, who now, in her place, bore the name Tess. She saw the destruction and death that would follow, the hundreds, if not thousands of innocents who would die. In that moment she knew she could no longer run from her past, no longer ignore her soul's call, for that which would make it whole. It was time to find the others like her, to face the ones who had abandoned her all those years ago, to awaken alone. It was time to face him.

She was going to Roswell.
