Miles’ wife ,you,was a scientist working with Grace, having your own avatar body. He remembers that. In fact he remembers a lot about you. How yoi, unlike him, were fascinated by Pandora, how you loved spending the time in your avatar body, exploring the jungle. He remembers every little detail of your body, the human one, he didn’t exactly get to explore the avatar one for obvious reasons…
Somehow his human self decided that it’s very important to remember you and now his recom self is haunted by the memories.
It gets even worse when he meets Spider, his son, your son, that tells Miles you are alive. Alive but not human anymore. Like Jake you had left your human body and became full Na’vi. But now it isnt a problem, it’s even better because, well, he is a recom himself.
And truthfully? He’d do anything to meet you again, to have you in his arms, to learn your body again. But life isn’t a fairytale. He doesn’t remember your last encounter, the argument about the Na’vi, your different beliefs about the people and the Pandora in whole.
So when you meet.. it’s rather gruesome. You attack him as his few crew guys, shooting your arrows at them,some other na'vi, neytiri and Jake,with you, killing one of them.
Spider: “Mom stop!”
Spider yells looking up at you,at Jake and at neytiry,Who too were like parents to spider here in the pandora world, and that’s when Miles’ brain snaps in need of seeing you, talking with you.
Miles: “Baby, my love”
His voice is soft, not firm like usually which honestly makes Spider cringe as he stood next to you,next to him were Jake,Who looked at his ex boss,Who Always hated navi,now in a navi body Just like him After he left him humans form to be with neytiry,and now they had Kids togheter,Neteyam, Lo'ak,Tuk another adopted daughter, Kiri.
