How possible is it that Hope was regaining her vision but kept quiet about it?
If it's possible she wasn't shot and didn't die, is it possible she was the shooter?
It wouldn't be that hard to fake being partially blind (hell, I had everyone at work convinced I couldn't hear the pitch the phone rang at for almost 2 years). Who would suspect a young partially blind girl?

Of course, next week we'll find out she was shot and I'll be wrong.
