Lisa Backwards.

Time moves differently for her.
Its faster when it should not be and its slower when she should be speeding up.
Trapped in a new parallel world every single second, she shivers, again and again but not because of the cold, because of the way her molecules get compressed by the airplane.
(We have long since come to understand the reason that lies beneath the veneer of distance she imposed on those around her.)
Maybe a time machine could do it, she could travel back at the same speed she is forced forward, find some release, a bit of explanation and maybe even some peace.
There are monsters in her mind.
