Points against it being paranormal:
Evidence points to it being a reflection, because a flash was used.
In the original it is 'very' grainy, without the cleaned up version I'm not able to see anything. So we can't rule out Pareidolia.
Points FOR it being paranormal:
The face is clearly NOT the boy's face from the photo. To me it looks like a female smiling.
It appeared more than once, so either 'its a very persistent reflection' or its a spirit.
That's just my nickel's worth of input.
