This is based on what I think will happen after the house burnt down, Amelia is at kais house and they comfort her. Abt Christophers death
Kai-Baby? Why are you crying? What happened?
Amelia - It's his birthday.. he would've been 11 today..
Kai-Hm? I'm pretty sure Scout is only 1 amy..
Amelia-No, no, not Scout.. I had another son years ago he would've been 11 today, but we were born without a brain..
Kai-Oh baby, I'm sorry, do you wanna cuddle? Or what do you want to do?
Amelia-I just.. I don't know. I don't know what to do, Kai.. was it my fault..? I gave away his organs after he passed, and a friend of mine told me I was a murderer..
Kai-Baby you aren't a murderer, You and your son helped so many people and saved so many lives I know you think it's your fault but I promise you it's not you couldn't do anything about that Amy
Amelia-Okay.. okay, I uhm I wanna give you something..
Kai-Hm?
Amelia opens her bag and pulls a box out, and opens it
Kai-Its beautiful Amelia..
Amelia-It was my father's.. He told me to give it to the person I'd want to spend the rest of my life with..
Kai-Amy..
Amelia-I love you, Kai. I knew I loved you when I first laid eyes on you, and I fell in love with you even more when you showed up in the parking lot..
Kai- I love you to Amy.. And I promise I'll be here for as long as you need me to.
Kai put the watch on, and a while later, Kai moved to Seattle. They and Amelia got their own house and lived happily ever after
