'The Walking Dead' season 3 is in full gear now, having aired its second episode "Sick" this past Sunday. There are many mysteries and details surrounding our favorite band of zombie-fighting comrades, but the most prevalent one is the apparent presence of the 'Harry Potter' character Luna Lovegood.

What happened to Beth Greene (Emily Kinney)? Did she get killed off already? No, she's still there. To the untrained eye, it may seem as though this not-so-popular character got the axe and was replaced by a cloned copy. But in fact, Beth is still weeping at one-legged Hershel's bedside... at least for now.
