How we cite our quotes:
[Edward to Bella:] "Afraid of a needle," he muttered to himself under his breath, shaking his head. "Oh, a sadistic vampire, intent on torturing her to death, sure, no problem, she runs off to meet him. An IV, on the other hand…" (24.53)
Bella fears needles more than vampires. At least, right at this moment.
[Edward to Bella:] "That's not the worst part, though," he continued to whisper. He acted as if I' hadn't spoken. "Not seeing you there on the floor…crumpled and broken." His voice was choked. "Not thinking I was too late. Not even hearing you scream in pain – all those unbearable memories that I'll carry with me for the rest of eternity. No, the very worst feeling...knowing that I couldn't stop. Believing that I was going to kill you myself." (24.181)
Edward constantly fears for Bella's safety. Though he is scared when James decides to track Bella, he's most worried about himself hurting Bella.
[Edward to Bella:] "When someone wants to kill you, you're brave as a lion – and then when someone mentions dancing…" (Epilogue.48)
Edward points out how ridiculous it is that Bella is afraid of dancing. When she's not in any real danger, her courage seems to drain away.
