The attic always scared James. It’s dark and dusty and lonely. He avoids going up here as much as he can, he’s only ever been up here once before and that was when Pandora and Lily first moved here. James had been living with them for a little bit, when Harry was first born: he knew how hard the first few weeks with Harry would be (especially since the war had just ended), and he didn’t want Lily to feel burdened or alone. He eventually moved out and into his own when Harry turned one. His flat was just a couple streets away from this one, so it worked out perfectly. He gave Lily some privacy and still got to be a genuine part of Harrys’ life. Plus he lived in the same building as Remus and Sirius.
