Theodore had not been planning on leaving Zach alone for the night. At the very least, they would be staying in the same house, but from the way Zach gripped his arm, he suspected it would be the same room. Potentially even the same bed. They hadn't done that since they were much younger, but under the circumstances, Theodore saw no problem with that.
It was very odd, how his father's will seemed likely to send all the people around him reeling, leaving Theodore to pick up their pieces rather than the other way around. That was alright, it had been that way for much of his life. Having people that loved him was all he needed, he didn't need them to put him back together. Helping others had always helped him, too, that was why he was a Healer.
However, he wasn't sure he could deal with another breakdown like Zach's. Not because he couldn't comfort them both at once, but he had not inflicted this on Zach knowingly; he would knowingly risk an emotional breakdown by telling Tracey, and he had never, ever wanted to hurt her.
But he couldn't leave her alone, either, especially if she was under the potion. He pulled out his journal without tugging his arm away from Zach, and let his cousin hold onto his arm while he wrote a note to Tracey, giving her the Floo address because he had not yet brought her here. "Tracey's on her way," he said quietly, and shifted to sit closer to Zach, lifting his glass of wine to his lips.
Maybe none of them would sleep tonight, maybe they'd just stay awake and wait for the sun to come up. Maybe Zach and Tracey would fall asleep and Theodore would stay up, stay up and read. Maybe by daybreak he would have answers.
