As Gabriella confronts Jesse after the soccer game, the two are walking off the field. After she leaves, he is again standing in the middle of the field.
When the toy Indian causes a rainbow to arch from Jesse's heart, the camera follows it and stops to show him standing on its other side. Even if this is intentional, she is also standing by him on this end, though she was never shown moving across with it.
The soccer team is shown to have both boys and girls on it, when in every upper school sports teams are divided by gender. Also, no coaches or referees are ever seen during the game.
Jesse assumes the gold star atop the Christmas tree is chocolate, but if it were, it would have long since melted (especially wrapped in aluminum foil). He also manages to "open" it by striking it with the plane propeller, and the chocolate star is sliced to shards instantly while the gold foil simply disappears.
