Regulus/Remus
Regulus didn't have much time, not when so many people were infected and their best chance at making a great potion was currently lying on a bed. Everything else had been put on hold and all research was geared toward those birds, their poison and any potion that might fixed it. They had tried the beozar stone, but to no avail, so the books were their only solution. Despite the seriousness of the situation, Regulus stopped in the infirmary a few times.
Remus had been asleep the first few times, but the third he was conscious. "I am very crossed with you," Regulus said as he approached the bed. "I don't even know what happened, but I'm certain that you did something extremely stupid to get yourself injured, because there's absolutely no way that a bird should have been able to get that close to you."
He brushed Remus' hair aside. "I can't stay long, but I wanted to see how you were doing."
