In an unguarded moment, Sif very nearly tells Thor that she will always be with him, but she holds that comment back as she squeezes his hand. If the loss of her memories is proof of anything, it is that life is full of uncertainty. She might make a promise now with the best of intentions, only to find herself swept up in circumstances beyond her control, be it tomorrow, or the next day. Nothing can be taken for granted.

"I'm glad, too," she says instead. "No matter what happens in the future, I am glad to be with you here, in this moment. And..." The mellow light of the fire casts her angular features in a sharp contrast, but her eyes are soft and dark as she looks at him. "I cannot take their place, nor would I want to, but... I will do the best I can to be there for you."

That is an easier promise to keep (if a less satisfying one to make), but she won't offer things she cannot give him. She wouldn't want to hurt him like that, to break her word to him. "And I am certain we will see them again. They were sent ahead to prepare a place for us there."
