Martine Bancroft: Michael, what's happening?
Dr. Michael Morbius: I went from dying... to feeling more alive than ever. Increased strength and speed... the ability to use echolocation... and an overpowering urge to consume blood.
Dr. Michael Morbius: How far are we allowed to fix something that's broken?
Mentor: Until the remedy is worse than the disease.
Martine Bancroft: I don't want to see you get hurt more than you already have.
Dr. Michael Morbius: This would be a cure.
Martine Bancroft: At what cost?
Martine Bancroft: You're up to something. What is it?
Dr. Michael Morbius: It's not exactly legal.
Suggested correction: If you look it's been clear that Strange's spell wasn't perfect. Eddie being brought into the MCU when he had no idea who Spider-man was...nor did he die. Electro's new-look and having no idea who Spider-man was. If anything Clea, in MOM basically said he messed up. So that last spell didn't fix things. It's clear this is what they are building towards. Nothing is fixed. Either way it isn't a plot hole for this movie. Post credit scenes are usually teases for other movies to explain.
