When Zach was finished reading the letter, Blaise took it, folding it carefully before replacing it in his pocket. It wasn't some keepsake for him to treat with the utmost care, but it was something he didn't want to lose. He kept going over the contents again and again, considering taking a trip to go see her before she really did die. But he was busy here, wasn't he? He had a lot of things to do. There was quidditch, classes, extra studying for MLE and his usual things. He couldn't just leave.
But he had to. Eventually he would if she didn't get better and hopefully eventually came before her death.
"Yes," he replied, running his tongue over his lips to collect any spare drops. His replaced the flask and began to head toward Zach's room, eager to get as messed up as last night and lose several more hours of time.
