I was reading that elsewhere, and thought it is great Kinney is getting an upgrade after 2 seasons.
There's a little hint of more things to come from Huffingtonpost
The world of "The Walking Dead" needs a little repopulation after the bloody third season, which saw us lose Sarah Wayne Callies (Lori), IronE Singleton (T-Dog), Michael Rooker (Merle), Dallas Roberts (Milton) and -- most shockingly -- Laurie Holden (Andrea) in the finale.
Additionally, Melissa Ponzio (Karen) will reappear in Season 4 as a recurring guest star, the sole survivor of the Governor's brutal attack on his own army in Woodbury. Coleman and Martin-Green play siblings who were an integral part of Rick's (Andrew Lincoln) fight against the Governor. Kinney has recurred since Season 2 as the youngest daughter of Hershel (Scott Wilson).
"The Walking Dead" earned its best ratings yet for the Season 3 finale, racking up 12.4 million viewers after breaking records for both its Season 3 premiere and midseason return.
Season 4 of "The Walking Dead" will see "a very different Rick," Robert Kirkman recently told IGN. "One of his main goals is to manage this situation with Carl and see if he can bring him back from this darkness that's crept into him."
Executive producer Gale Anne Hurd also promised, "we are going to amp up the threat of the walkers," in Season 4, "because they've started to seem like a manageable threat. They are not a manageable threat ... But, it is the people who you think you can trust who betray you, that you have to fear. It is the monster inside you. We all have them. How do we keep them in check?"
So, Hurd promises more zombie action. I thought that is where the series needs to go. If we are to believe the walkers have overrun the earth--or at least North America--then the series cannot settle into a general domestic drama format.
I think everyone predicted the Carl problem was going to be a major plot of S4. Let's just hope he does not do something stupid, such as:
1. Leave Rick's group to join the new enemies--including the Governor (turning a son into a revenge weapon), based on his "kill or be killed" mentality. Perhaps he's abused so much, he will be on the edge of suicide.
2. Carl goes off on his own to kill new enemies--a misguided attempt to prove to Rick that "kill or be killed" is the only way to live.
3. Is kidnapped--or conned into helping the enemy. Either way, he leads enemies back to the prison, triggering the final battle with the Governor.
Looking forward to season four!
