Neal is a child, taken in by Peter and Elizabeth
Okay, so this fic I read years ago and being the smart person I am, didn't bookmark it. Basically thie fics has Neal as a child who lives with his mum. I remember a part where they're shopping and she tells him to hold a can and walk out of the store with it. Another scene is where they're in their flat, and she sees something out the window and tells Neal ti hise and that it's a game and he can have anything he wants if he wins. When he is adopted(?) by the Burkes he draws a missing poster for his mum.
If anyone can tell me what fic this is I will be so gratefull. If it helps I bleieve it was on fanfiction.net
