Baelon had not seen his sister in years. Not since he had outed her to their entire family, and she was sent away. It had taken him years to even think about it.... he had been in the wrong for betraying her as he did, he'd put that much together years ago.
Alyssa was just always on his mind, and she was gone. His sister... he was scared to see her again for he knew she loved him; he wasn't sure how much. He could see the broken look in her eyes as he watched her look away from him as quickly as they made eye contact. He was reminded of the broken eyes she'd given him when his father decided to send her to the north and not let anyone see her for several years. Her husband was dead however, and she was back.
She barely spoke to anyone after returning, simply greeting the Old King, their mother... already dead. It felt like Baelon's solo was being sucked out of him. He took a deep breath and later, while she was sitting in the gardens alone, he decided that it was very well time that he finally approach her. If there was even a small chance to fix what they once had than he would try... even if it took years.
