Cube/2 Hypercube/Headscratchers

• If Kate was sent into the Cube to find Alex Trusk, you'd think she'd know a little more about them than their name, like maybe that instead of being a Russian male, that they're a blind Korean(?) female who goes by the name "Sasha" via an obscure Russian nickname route.
• If Max and Julia are in an accelerated-time area, wouldn't they have just had their sex Really Really Fast, rather than dying of old age while having it?
  • That's not how relativity works anyhow, but due to movie physics they're perceiving time as normal when, in actuality, it's moving very fast relative to them. It doesn't make any sense no matter how you slice it, unless they emerge normally at the end.

• How about the whole all the cubes converging at the time shown on the watches. How does that make any sense in a world where time is completely relative and not entirely linear?
