When you have two mirrors facing each other producing an "infinite mirror" effect, does it take time to "draw" each additional mirror?

You know when you have two mirrors facing each other and there are thousands of smaller and smaller reflections inside each reflection. Since light travels at a finite speed, shouldn't it take time for each of these smaller reflections to be produced? If you could slow down time, or had mirrors far enough apart, shouldn't you be able to see each additional reflection pop into existence? Help me science.

You are correct, but are a few practical matters that intrude on this.

First, mirrors are not 100% reflective.  After 500 reflections, less than 1% of the light is left.  That might sound like a lot, but if your mirrors are a meter apart, that takes a little more than a millionth of a second.

Then you got alignment.  If the mirrors are 1^o off, the first reflection will be 1^o off, the second 2^o, the third 4^o, and so on.  For that 500^th reflection to be on target, you would need alignment on the subsubatomic scale and beyond.

Finally, you have the Dawes limit.  Because light is a wave, diffraction introduces a level of blurriness, even with perfect optics.  With a 1m mirror, the Dawes limit would be reached at about 500m, or 500 reflection if the mirrors were 1m apart.
