Sirius/Lily. (And Harry!)
As soon as James had reappeared in the waiting room, Lily was by his side, grilling him for all the details. Based on the message they'd received from the Healer, she doubted Sirius was in a state to want to answer the same questions over and over. The more she learned, however, the more ashen her face became.
Standing in the doorway to Sirius' room a few moments later, it was all Lily could do to hold back her sniffles. Her eyes were already shining with unshed tears, and she was doing everything she could to hold them back.
"Hey, there," she softly greeted Sirius, moving quietly into his room, Harry cradled in her arms.
