wait gjghkh going to expand on this because i have more thoughts now:
"tara is probably trying to forget that amber ever existed because it’s easier for her to erase all of her memories with amber than to acknowledge that she never really knew her bestfriend, someone that had been there for her her whole life. But no matter how hard she tries to move on, everytime she looks at her hand is a painful reminder as to what her best friend had done and no matter what that scar is never going to go away it’s the only thing truly tying her to amber. So because of that they’ll always be connected and she’ll always have to think about that first night (the opening scene)
