Plot hole: Vulture from the MCU is pulled into the Venomverse due to the spell cast by Doctor Strange in No Way Home. This is absurd. The first spell pulled characters from other universes into the MCU, while the second spell brought the characters back to their proper universes. Neither of these spells involved pulling characters out of the MCU and into the other universes. Vulture of the MCU was already in his proper universe. No explanation is provided for this.
Character mistake: Doctor Bancroft mispronounces "Nobel" when reading the headlines to Michael. She pronounces as "noble." It's a famous award, especially in the field of science and someone as smart as she is suppose up be would know how to say the name.
Suggested correction: Honestly, I just rewatched the scene in question, and I really wouldn't consider that a character mistake. It's not a super egregious mispronunciation to begin with (the difference between the sound of the words is quite minor), and based on the way she speaks and the fact she has a bit of an accent, it just seems like more of a personal affectation than a character mistake.
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.
