Harry froze up. He almost felt as numb as when he'd been tortured by Voldemort, taking in the news. People had come back from the dead. His Godfather..
Harry followed Remus' line of site and turned around, staring at Sirius Black. Remus wouldn't joke about something this serious and to even think about trying to play with his mind would have been so far beyond him.
"S..Sirius." Harry didn't stop himself. He ran across the room and threw his arms around his Godfather, hugging him tightly. He was real, breathing, solid. He didn't want to let the poor man go, but it was clear that Harry was smiling again. First time in a very long time.
