I went back to check and it happens at 13:05 going forward. I continued to watch because I wanted to see the dog but never did. However, at 15:30 there is something that makes a very brief appearance on the left side, where the tree is. So someone was out there doing something.
I also noticed during the outside workouts that there is something that looks like a ladder in the background but it appears to move from workout to workout.
Believe it or not, I do actually see what they are doing and follow them. I don't spend all my time looking at the background.
Leonana, it moves from the left of the screen toward the right, from the roof toward the pool, and is right over Jessica's head in midflight.
