My wife missed 905, and I wouldn't tell her what happened. We watched it before 906 last night. Upon [my]watching a second time, I noticed something that seemed odd at my first watching, but this time I rewound and watched closer. When Rick's hallucination with Hershel was ending, Hershel had his hand on Rick's chest as he told him to wake up (on Rick's left). If you watch the sequence carefully, for a moment when Rick is back in reality, you see Hershel's hand on Rick's chest as Rick is on the horse. I don't know exactly what it's supposed to mean (the TWD writers always do stuff like that for a reason though), but it was VERY cool!!
