The Tie That Binds

(Mostly book canon, but I may borrow some things from the movies if I like it/it fits/I forget something lol) Thomas and Teresa both make it through the Flat Trans to Paradise, battered and scarred but somehow still alive. Even so, they know things won't just immediately go back to normal. They've watched many of their friends die in front of them, and the trust between them is still incredibly fragile. Now, they must attempt to mend the tatters of their relationship, process their grief over the loss of their friends, and deal with the burgeoning of an inexplicable and even deeper connection than ever before. Thomesa AU after the end of TDC where it's Brenda who sacrifices herself for Thomas instead of Teresa, and their telepathic abilities slowly begin to return - despite the removal of their implants.
