Continuity mistake: When Edward is showing Bella the bruises on her arm and shoulder, his wedding ring is on his right hand. They are looking in a mirror, but the camera is on Edward, not the reflection.
Continuity mistake: When Bella is first seen pregnant, she is wearing grey pants, a blue shirt and navy jacket, Edward is wearing a brown shirt, and Carlisle is wearing a blue mock turtleneck. On what is supposed to be the next day (and after having seen them wearing different clothing), all three are wearing the same clothes again while in the library/makeshift hospital room. They are discussing a cracked rib that was causing Bella pain the day before. These scenes were obviously meant to be back-to-back, but were rearranged in editing.
Continuity mistake: After Renesmee's birth, there are two smudges of blood on Edward's right cheek. While Edward works to transform Bella, the blood spots appear and disappear between shots.
Continuity mistake: At the end, just after Renesmee's birth, the blood pattern on the front of Edward's blue shirt changes within minutes from being one solid red mass to more mottled.
Answer: He's merely justifying why Bianca should be killed. While reading the note, he notes that she misspelled "Carlisle", then surmises she'll also make grammar errors. Aro does not tolerate imperfections, has little regard for human life, and most likely intended to dispose of her.
