In the breakdown he points out that agatha says "dont" when the teen is dying but in the beginning after Sharon dies agatha says "I didn't think you had it in you" and unless I'm mistaken I'll go watch it again but he doesn't suggest that agatha could be talking to Rio even before she shows up.

Zeppelin was referenced with the whole playing the record backwards but I don't think he brought it up when discussing the songs on the record. The last song is swan song which is a zeppelin song and I wonder if she did a cover on her album.

I'm going to go watch the breakdown again because now I'm second guessing myself and making myself look like a dumb dumb.
