In a world where all reflective surfaces instead show a view into a parallel universe, Suyin stands between two mirrors facing each other. These mirrors normally would result in an infinite regression of reflections in our world. What does Suyin see in the world with the magical property when she looks into either mirror? Provide a brief response.
In a world where reflective surfaces show a view into a parallel universe, the property of infinite regression of reflections would not apply as each reflection wouldn't show Suyin and the room behind her repeated endlessly. Instead, when Suyin looks into either mirror, she sees into a parallel universe. 

If the view into the parallel universe happens to be an exact copy of her own position and surroundings (which is statistically improbable), she might still see what appears to be a reflection of herself, but it isn't actually her or her room; it's her parallel universe counterpart and their room. If the parallel universe is different, she sees whatever happens to be in the position mirroring her own in that universe.

Since each mirror is a gateway to different parallel universes, looking into one mirror shows one parallel universe, while the other mirror shows another. There's no interaction or regression between the two because they are separate windows into distinct universes. Therefore, Suyin sees something different in each mirror, depending entirely on the respective scene of each parallel universe at that moment.
