"I'm sorry," Sirius gritted out, keeping his eyes tightly closed. "I want to remember, I do."
He took a deep breath, banishing the pain and slowly straightening up.
"I'll try again." he turned back to Remus. "Tomorrow?" It was more a plea than a question. A desperate need to know that Remus would still be here tomorrow, would still want to help him. That Sirius would still be himself in the morning.
