Further ahead he might catch sight of someone else following that... apparition(?), though Riku was having a bit of a harder time, given that he doesn't have glasses.

It was getting frustrating quickly though, and Riku's just gritting his teeth as he decided that maybe it was time for a change in strategy and called for Way to the Dawn, taking a deep breath and focused his magic a little bit differently then usual.

It took just a whisper - "Freeze." - to invoke it and let Deep Freeze cover the next several meter in front of him, a thin layer of ice covering the street.

At very least, being able to follow it that way instead of searching constantly for a source of reflection, didn't make him question his sanity quite as much. Even if it did mean a little bit more work for him.
