Even if the Cullens didn't tell Bella about the car chase (and I can definitely see them not doing that), wouldn't people in the hospital be talking about it? Wouldn't she realistically overhear staff being like "wow did you hear about the 27 car pile up?" Wouldn't some of the people injured be brought to the same hospital? If Bella had a TV in her room she or Renee might catch some of it on the news.
She sees Ponytail Mom interviewed, talking about how she was run off the road and right before her car was stolen she saw the most beautiful man ever and then inexplicably passed out and Bella just turns to Edward like, "that was you, wasn't it?"
"No. Carlisle. I mean wait, what? We had nothing to do with that."
Its very jarring to read Midnight Sun and see how frequently they call Jasper 'Jazz' when Meyer didn't come up with that nickname for him until Breaking Dawn. It's just very weird to see them calling him that so early in the chronology.
If anyone in this fandom dies and finds themselves born in the same life again - refrain from going on tumblr. You think 2012 teenagers are ready to hear you rant about how you really hate the carlisle x bilward (Resume and Jacobs firstborn daughter - short for Billy and Edward) book from 2087 was too focussed on how Esme was dealing with the fact that Carlisle was hitting his technically unrelated great granddaughter?? Instead, just kill Steph and save us all this regret
