Albus had been exploring the island just a little bit. He had gone to see where he would be making his hammocks, and had decided that the little run-down shack just needed a few things to pick it up and make it into something awesome. He was rather excited to get to work and learn this new trade.
After his trip around the island, seeing what he could of the place, Albus headed back to the Bungalow. From what he had gathered, he was living with his Grandmother and his father was on the way over to meet them both. It was a bit odd, meeting his father, who he had known for the past 23 years of his life. Though maybe that meeting was on his father's behalf. Albus was excited to meet Lily though.
He didn't knock on the door when he returned, as this was his new residence as well. There was no need to knock, it would have just been awkward. Right within the door though, already a younger version of his father stood before him and, who he assumed was Lily. She had startling green eyes, just like Harry and himself.
