She was the only one that could hurt him? Then what did he think that he was to her? When he left, when she was told that her papa was dead, she died on the inside. And it took her years, several years, to become aware enough, to understand her abilities and what she felt enough, to know that he was still alive. And knowing that only made it worse. Knowing that her father was not dead, that he had willingly left her behind, was even worse than thinking that he had died.
As for trying to find him, she had been trying to find him for as long as she had been able to travel on her own, which hadn't been for very long, granted, as her grand-pere kept her on a tight leash. It wasn't until she stopped insisting that Adrien was alive and seemingly accepted the fact that he was dead that she was left to actually try to track him down. And she had stopped at nothing. That's why she was here. She had killed to find him. And it was all in vain. At least that was the way that it felt right now.
"If you didn't, then who did?" She asked, her voice cracking ever so slightly. She wanted to just run away from him, wanted to push him away from her and just leave, but she couldn't. She loved him more than anything or anyone and no amount of hurt or anger could or would change that. So instead, she simply closed her eyes tightly, trying her best to ignore anything he had to say, trying not to let him get inside of her head again because, if he did, then he could hurt her again, but denying him would be like a Priest denying Christ. Maybe even more difficult than that.
"Je suis mort quand vous m'êtes parti, le père." She whispered, resorting now to their native tongue for it was so infrequent that she could speak to anyone that way. "Comment peux-je vous pardonner probablement cela?" Her hands moved up to rest upon his arms, fingertips soft against his warm skin. "Comment peux-je ne vous fier pas à me partir encore?"
Translation: I died when you left me, father. How can I possibly forgive you? How can I trust you not to leave me again?
