Logically, Emma knew it was part of the construct of this place. They were so entwined, relying on one another in this place, battling what it threw at them, through near death and sometimes actual death, that it forged connections so deep they were almost part of them. She knew that was how it started with Jefferson.
He'd been by her side for absolutely everything in this place, almost losing him one time before, enough that now she could barely stand to stay away for a number of days. A few hours was a hardship right then. He was the first person she thought of when she was scared or hurt. He was the one person she was most scared of losing too.
She knew that there was still home to deal with this, to cope with the Dark Magic that would be there, but she wasn't there right now, and that was enough to stave off that guilt trip for a few more days maybe. And it might be a good thing, just how badly this was affecting her, the fact that she wasn't just shrugging off her casual murder of a person who had done literally nothing to her, at least this place hadn't numbed her to the worth of human life so easily.
"I think it's still there. Something of it. I feel like there's something that shouldn't be there, just sitting inside."
