Quinn is a time traveler, yes, she has traveled to the HP magical world.
A standard orphan, but it doesn't matter, she can smell and eat and has magic power. Look, God will reward her with food, so she doesn't have to worry about having a way out.
So she whistled and sang songs, learned magic and made friends, played pranks and broke into restricted areas to play, and then helped a forced guardian to defeat Voldemort. Life was so beautiful.
Spread joy wherever you go.
It's none of her business to prophesy or anything like that - it's strange that the time turner of poor quality and destroyed by the death curse caused her to travel through time again.
Then she realized, wow, it turns out...
