In the The Crumbling Crow (bar), Hogsmeade
He was making an effort.
He was out and about.
He was talking to people.
Sometimes.
At the moment he was sitting by himself, in a dark corner, staring out the window. In his hand was a mere glass of water. On the table before him, an open book.
As the others drifted, in and out, he remained a constant. A dark statue.
But he needed something new.
When he got up, the dark cloak poured down around him. His frame moved over the room in quiet strides, a long, skeletal thing. Propping his elbows on the counter, he stole a look at the selection of drinks on the other side. But his eyes wandered, and he recognised the face of the woman beside him.
"Congratulations," he said.
"On Headmistress."
He reached out a hand - he didn't think they'd been formally introduced.
"Lukas Altair. Former Hogwarts Professor," he explained.
