Panel 1: bright university lecture hall, Oscar in shirt at a whiteboard drawing a physics formula, students watching. Panel 2: students smiling, taking notes. Panel 3: close-up on Oscar's wrist with a discreet smartwatch or device starting to blink. Panel 4: Oscar glances at the device, slightly worried, classroom in the background. Panel 5: later in a locker room or office corner, he removes his jacket and we can see a hint of the glowing superhero suit under his shirt.
