can it be true? is the breaking dawn a copycat?

Jordan Scott Accuses Stephenie Meyer of Plagiarizing Breaking Dawn

-- Both books contain a post-wedding sex scene
-- Both books contain a scene about a woman who's sick because she's carrying a child with "evil powers"
-- Both books contain a scene with the death of the main character's wife

And according to Scott, the dialogue in all of these scenes -- and more -- is extremely similar.
