You would need to presupposes an infinite amount of time to assert an infinite number of reflections even in a perfect thought experiment.

Thus, it is impossible for the argument to be sound.

Thus there is a limited number of reflections. Additionally the light would have to originate from within the mirror otherwise it would reflect out of the mirrors. Finally the speed of light is finite thus the number of reflections is finite.
