There was so much more he wanted to tell him, and yet, now - whenever now was - always seemed such a poor time. A part of him nearly wished he did not know of his son's loyalties, his connection to Severus...
Well hopefully that would change soon enough. Severus was a halfblood, with any luck he'd die in the epidemic and Draco would come back to his senses.
He nodded and stood up, walking over to his son. Wondering if he should say something a bit more meaningful, take the risk, explain what Draco should know, he hesitated, but then decided not to and squeezed his shoulder. There would be plenty of time after the war.
'It was very good to see you too, Draco. I'm proud of you.'
