To say things since his arrival had been strange could have been an understatement, from his own sort of escape from Azkaban followed immediately by what he could only call his death, to a resurrection, and meeting Jamie who was impossibly Harry's son, and then James' arrival as well. He had no shortage of things that were pulling his attention this way and that so the offer to sit down and talk with someone like this seemed like a good idea. Neville had said he was the son of Frank and Alice, which of course shouldn't be true either, and yet Sirius was beginning to be able to wrap his mind around the truth that things here simply defied what should be.
It helped to have something to do, he could focus on that instead of letting his mind wander. So he made his way down to the greenhouse that morning, curious what was growing inside, it was smaller than the ones at Hogwarts, but that didn't mean anything really. He knocked when he found the door locked and then was let in a moment later.
"Hiya, yeah." Sirius took the hand Neville held out to him, "Sirius." He said knowing of course it was unnecessary. "So this all yours?" He asked, curious as he started looking around, there was a lot familiar about the space, and Sirius could appreciate that after so long without things like this.
