There isn't a lot that Nico remembers about his mother. That's typical though, since he was stuck in a casino in Vegas for over seventy years. Still, he feels as if he should remember something important: her laugh, her smile, her smell, her eyes, the sound of her voice.
But no, that's all a blur to him. The only thing he does remember is a pair of yellow shoes. Just a pair of classic, yellow high heels. He doesn't exactly know how he knows that they're Maria's, he just does.
This does not comfort him. In fact, it frustrates him to no end. Why is it that he can remember something so pointless and nothing more? Is that really so much to ask for? All he really wants is a memory of them laughing together or a snapshot of a conversation or even just to remember her face more clearly.
That's it. That's all he wishes for: to remember her.
