There wasn't really any rhyme or reason to him having found himself at a park of all places, he just had. The wandering had left him a little tired, wanting to sit and so he found a series of benches in front of the park. Azazel watched the children play, never really seeming to focus too much on anyone in particular.
It wasn't until the pink haired lady walked into the park with her stroller that he seemed to notice anyone in particular. Pink hair wasn't necissarily that unusual, but he watched her none the less. And as her son was taken out he couldn't help but notice his own brand of unique hair colour. Azazel smirked a little leaning foward and resting his knees on his elbows. It was the woman's hair spontanously changing to match her son's that got him to his feet.
Casually the demon, in the guise of a fairly normal looking middle aged man, moved towards Dora and her son. He offered the young woman a warm smile, keeping his eyes their neutral brown colour and not his charateristic yellow. "Interesting talent there," he mentioned but in no way seemed freaked out by the fact she had just changed her hair colour.
