Gaius wasn't at the point to be able to make a flip comment about Sirius' propensity for disappearing. Not yet. But he nodded at Remus' words as he sipped his drink and leaned closer to Serenus' solid warmth. "It is remembering how much I do have that helps most," he said, then looked up at Serenus, his eyes misting over a bit. "I have the best brothers in the world, and Serenus has helped more than anything. The whole family has, really, but... Serenus understands." He didn't explain why Serenus understood - Remus had been there, and the parallels weren't difficult to see.
