I can see why folks would be confused about Shane as a character, and I think thats because they show a completely different character in the flashbacks, even when we first meet Shane in series one at the campsite, he's not shown as dark, and impulsive a person as he is becoming.
Now I cant work out if Shane had a dark side to him all the time and was very good at hiding it. Or this change of character is just unrealistic, done by the writers of the show to make things interesting. He's gone a hell of a long way off track!!!!!
Also I find it hard to believe that Rick and Shane would be such good friends, because they are at complete oposite views on everything - well at least since Rick returned from his Coma.
I cant help but wonder was there more of this in the past and Rick just didnt see the darkness in Shane's personality. The chat they had in the woods about Shane's womanising ways, and Rick being the complete oposite - would these two men really be so close, would Rick really trust a man who was obviously so shallow close to his family.....
Or again is this just an unrealistic change that the writers have done to try and make this interesting....
Ive not read the comics so cant comment on how close this is all to those. However, I do sometimes think writers throw things in to shock, some cheap tricks I find - I dont always appreciate them, can be a bit annoying.
I forgot to mention what I thought of Andrea - she's making mistakes in her bid to be a tough woman. Shooting Daryl being one mistake, and Im sure we'll see a few more wrong choices from her this season.
