Actually I'm starting to think Sasuke did protect her by choice (expressions do say something) but she didn't know of his new ability. It's after Naruto saved her she saw his new eye. She had no idea he rescued her too. Just like when they fist reunited. He was at her side with Naruto when the spawn came at her.Did people not see the Limbo clone on Sakura's left?
FFS, Naruto was able to sense them, but now Sasuke can't see them?
Wow....
