"I... couldn't sleep at Haven's Loft," Gaius said, turning his gaze away and flushing a bit. "Too many memories, too much pain." He could tell that Regulus was withdrawn into himself, and he ached for the fact that Regulus didn't have the support network he himself did. "I want you to know that I'm here for you, my friend. If you need to talk, or just not be alone." He couldn't invite Regulus to Serenus' house, but hopefully Serenus would make the invitation himself.
