'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.

But in fact, Beth is still weeping at one-legged Hershel's bedside... at least for now.
