[Anna can't understand why Lorna is being so self-flagellating about this. Or rather, she doesn't understand, not until she thinks back to all those years of silence from Elsa. How she'd felt like it was something she'd done wrong, how she'd blamed herself for somehow, unknowingly, driving her sister away from her so forcefully that she'd locked herself away in her room for fifteen years.

And then she gets it.

She doesn't let go of Lorna's hands; quite the opposite, she squeezes them that much more tightly with her own petal-soft fingers.]

Lorna...it's not your fault. You didn't ask for that. You...you're the kindest, sweetest person I've ever known. That isn't you. And—

[She lets go of one hand and reaches out to tilt Lorna's face upward, to rub a thumb over her soft, smooth cheek, and give her an encouraging smile.]

No matter what happened in your past, I love you. I love you so much, Lorna, and nothing could change that. I promise.
