Having stared at a lot of photos in my days, I think the photo is AI generated + actual photo + photoshop etc. (background for instance) and a similar person of Sebastian or just his face generated onto a similar body or vs.versa).
What strikes me as odd in the pic is 1. it's only 1 photo, not a live , not a series, not a vid. Usually, people press that photo button several times, especially if they really want to capture something.
2. the lighting is off, and the sharpness vs. blurriness in places.
3. The relaxed postures of the people in the pic at such an odd location "drive in" is odd. As well as the driver who took the pics closeness to the people.
That said, we don't have the raw or a better solution one. If it is not AI (in some way or photoshop) I would simply believe it was either 1. taken at another time 2. it is just someone who looks like him and the other person looks "like people" or have been edited in.
Parents want to see the sign of life of their child even if there is none. Or they want to cover something up.
