What kind of letter would they write but never send?
Well, here we are. This is one that I've thought about a lot, but out of fear of being cliche, have stalled on answering. It'd be the hardest for her to write, but I also think it's one that she wrote very soon after being painted anew.
To Verso. Another letter of apology. But also one of blame. In the process of writing it, or perhaps even just speaking it aloud, it would be an attempt to believe that all the emotions she has toward him after the events of the search and rescue are valid. That they can all exist at once and none means less than the others. In fact, I'm quite certain this is not a letter written down. She wouldn't want it to exist without context. She's no writer, she'd be adamant that she wouldn't be able to convey those twisted emotions in the written word.
So, a journal then. Recorded on a night plagued by insomnia. Addressing him directly, as she cannot bring herself to do it in reality. A broken mess of thoughts that she'd be stunned anyone could make sense of. Beginning with genuine loathing. There's hatred for him buried deep, driven through her by his sword and left in an invisible wound. It has scarred her. She was never one for hatred before the fracture, but she learnt it well alongside reasons and ways to fight. She'd tell him she hates him. For not trusting her with the truth. For not being honest about his fears. And for thinking that the only way to resolve the problem was to kill her. I think, in truth, she hates his actions, rather than all of him. But god, it's hard for her to separate the two.
Just like she can't be devoid of the guilt she feels for all of it. Towards him. She'd fall apart as she admits to it. She'd never intended for the interrogation to escalate as it did. She'd admit that she's sickened by the fact that one of the blades ran through his body was hers, guided by her own hand. That on the nights that she doesn't dream of his sword deep in her chest, she instead does the same to him. Meeting his eyes every time.
This letter would be everything she feels she can never tell him. For his own good. If she does, she fears she'll want to hurt him again, or worse, that she'll break down in front of him and make the life he does not want even harder. Because yes, there's still sympathy there.. And I think for Julie, withdrawing from the world, from the truths she needs to face, is the only way she can get through the days and finally find a reason to keep on living.
