Kili/Kallian
When it comes to magic like this, it isn't a matter of forgetting, at least not as we know forgetting. We all had our minds wiped clean against our will, and new thoughts and feelings that we didn't want shoved into the empty space. The one thing that all of us there had in common was that all the things that matter most to us were taken away. Our selves and our lives were stolen from us, including the people we love. You didn't exist there because we were cursed. Tauriel would never forget you, just as I would never forget Alistair. For the weeks we were gone, we were made into other people who never knew you, and if she is anything like me, she was horrified when she came back and realized what happened. None of this means that you don't matter to her, or to Thorin.
