Miam Metro work ethic:
Allegedly having scanned the entire room for traps, but then missing 5 big fucking bowls of blood at the ceiling? That's just bad form.
Not to mention, are we really meant to believe Travis killed the professor and orchestrated that entire scene while Dexter was stuck in the elevator??
I suppose it's possible he went there beforehand, but that's not the impression the episode gave. Otherwise, why go through the trouble of trapping Dexter in the first place?
