Argh! Someone help please! I read a Snarry (convinced it was in the Snarry Games) where Snape is a portrait, and Harry visits him, throughout the years with his kids. He has sex with Draco in the room of requirement, which is where Snape's other portrait hangs and Albus takes Snape there to catch them at it, I think. Anyway, Harry ends up dying and they get together in the portraits. At one point, Snape dissapears for ages, roaming through all the different countries and places. I REALLY hope someone can help me find this as it's driving me bonkers!!!
