The Walking Dead - What Is Your Favourite Season 1 Episode?

As announced yesterday here's a final poll to pass the time until the premiere tomorrow night. Tomorrow I'll post a summary with the results of all polls combined, so make sure to also check out old polls you haven't voted on yet.
And that is today's question:

Days Gone Bye
Sheriff's deputy Rick Grimes wakes up in the hospital after having been shot while on duty and discovers that while he was in the hospital, something has happened which causes the bodies of the dead to reanimate and attack the living. The town he lived in is mostly abandoned, with many dead roaming the streets at night. Believing that his wife, Lori, and son, Carl, have most likely fled to safety in nearby Atlanta, he grabs a stock of weapons from the locker of his police station, and sets out to find them.
