My God, really? Are you THAT delusional? The Governor is dead. Just because you don't see doesn't mean it doesn't happen! You know what we saw? We saw the Governor getting stabbed in the chest. You know what happens when that happens? You suffer from pneumothorax, which is a deflated lung. You know what happens when you have a deflated lung? You can't breathe unless the lung is re-inflated. And with where he was stabbed, there's a good chance that she nicked his heart and he'd be slowly bleeding out on the inside. So between those two injuries alone, with the lack of medical facilities and modern medical treatments, he would be dead in about an hour or so. And then we see Lilly raising her gun, aiming right and the Governor and firing. That means she shot him in the head.
By your statement of "because we didn't see it, he's alive", by that logic, then Merle should have his hand, since we didn't see him cut it off, and Sofia should be alive because we didn't see her get bitten by a walker, die and then come back to life. We didn't see those happen, and we got a clear indication of what happened. But what did we see? We saw the lead up of Merle trying to get the saw. We saw Sofia coming out of the barn with a freakin' chunk of her neck missing. Both events happened off screen, both of them occurred.
We saw the leadup to the Governor's death, be it dying from bleeding to death, being unable to breath from a deflated lung due to the puncture to the thoracic cavity or getting a bullet to the head. He's dead. Period.
And BTW, straight from the actor's mouth
in this interview.
What was the conversation like when you found out the Governor would be killed off in the midseason finale?
I did get the death call [from Scott] and it's always a sad one. I knew the Governor wasn't someone who was going to be in it forever. I was very sad because I loved being in the show and working with everybody. Then the double whammy of also being the person who brings Scott Wilson's participation to an end was really heavy. All the episodes are all very demanding and shocking, and we had that at the end of last season when Laurie Holden (Andrea) and Michael Rooker (Merle) were both killed. It's something we go through on The Walking Dead and it's hard when it's other people, but it's just as tough when it's yourself.
That italicized part is important. Why? Because every character that has died in the show, the actor received that phone call prior to. If the Governor was still alive, that phone call never would have been made. It was. The Governor is dead, just like in the comics, a mad dog put down by a bullet to the head by a woman named Lilly.
