It was almost like flying, soaring through a vortex of his own memories. Things he hadn't thought of in years, places he didn't remember being too, people he's forgotten, all streamed by along with mundane and the everyday.
When they stopped at the memories of him and Remus Sirius couldn't help but cringe. He didn't want Snape to know anything about that. He was glad when they moved on quickly.
He knew what was coming as they settled on the memory of the Valentines Ball. He remembered most of what happened, but this was different. This was seeing it, in stark black and white, and he cringed away from it, his body whimpering involuntarily. He didn't want to remember this. Then Lestrange was there, and they were taking him somewhere, and then there was darkness. Nothing. Sirius was floating, completely unanchered. He struggled trying to find Snape, when something exploded, shards of black ripping through the darkness.
He was in a little room, mostly naked, tied to a chair. A man was looming over him, a man with a snakes face and red, terrifying eyes. He pushed harder, wanting to see everything, to know what this man had done...
PAIN, white hot and searing, struck him like an arrow between the eyes. He began to scream, body bucking off the bed, muscles taunt and quivvering. He could hear malicious, evil laughter echoing in his mind, and a word, a name, the only thing he'd brought with him from that dark place...
"VOLDEMORT!" Sirius screamed, vocal chords tearing with the force of it, before passing out cold.
