When they came back downstairs after seeing what could be Teddy’s room as well as a couple of extra rooms that they could use for guests or hobby spaces, Sirius led him back towards the conservatory. There was a small den off to the side that Remus hadn’t paid much attention to on their first walk around. Now, he saw that it held an upright piano, apparently left by a previous owner. Sirius sent him a wink and sat down at it.
