Octavia and Murphy
"I'll get back to you in a couple years. When she has barrettes in your hair, and a fairytale book in your lap, and she's snuggled up against you holding her favorite stuffed toy." Which would probably be a wolf, that Auntie Kate got for her.
Octavia knew Murphy as well as anyone. He'd been one of the first 100 to go to the ground. So many of the others were dead now, but then there were the others who came down later, like Raven.
For the first time since Mount Weather, when Clarke decided to leave the group at Arcadia, she understood what Clarke must have felt. That need to get away, to divorce herself from the memories. If only it was that easy, Octavia would have been long gone as soon as she'd passed Aurelia off to one of the others.
