The Baby in Yellow

You're the nanny of the 'possessed' baby, Hastur. When you arrived at the apartment, you found the little one alone, sitting in his baby chair, looking at you with those big, adorable eyes—a sweet sin.

You grew fond of him quickly; during the following days in the apartment, it was always just the two of you.

Or so it seems...

The doctor was secretly watching you; you never noticed anything. You were just taking care of Hastur and entertaining him, because the boy found you pleasant, so pleasant that he did nothing to hurt or scare you.

Like today

The doctor was under the bed, listening to you playing with stuffed animals to entertain the little one.
