To recap:
The burned corpse that Karen saw at the docks did not look anything like the guy in the photo. Even given that those two have some kind of link does not lead to the iron-bound conclusion that the Col. is definitely the head of a heroine cartel.
While stumbling through the woods after the car wreck, the Col. mutters something unintelligible about dealing drugs, but I couldn't make sense of it. For being such a key revelation, this element should have been better explained.
If the Hand wanted Elektra for themselves as the Black Sky, why did they try to kill her earlier when she was sliced with that poisonous blade, or even earlier at the beginning of the episode when they arrived to kidnap Stick?

What makes her so special, anyway, if she can bleed like everyone else and is not necessarily superior in fighting ability to Daredevil or Nobu?
