Errrr, I don't like that idea.... It seems a bit too unreal, I know the zombie apocalypse isn't realistic but the difference is, you saw Lee dying and you know what happens when you die. He was getting weaker and weaker, paler and paler and his eyes went that murky greeny yellow and he looked like he was getting tired and exhaustion was setting in when you got to the underground place because you think Vernon will be there with Clem. And I did cut my arm off because I wondered what would happen (turned out I nearly threw up).
And now moving onto Kenny- the Marsh House was surrounded by LOADS of zombies and he probably had ran out of bullets when he was trying to get all those zombies off his back in the 'Maw of Darkness' aha :L Omid

anyway, I really think that there is a slim chance that Kenny is even alive and it is probably a dead end down there, so he probably got trapped or cornered and he shot down as many of them as he could but he couldn't find any way out because it was SO dark down there. And he would of been unprotected even if he had of gotten out of the darkness. He would of been eaten straight away.
I'm sorry but both characters dead, I loved Lee we was a great guy and I never saw him as a monster, although there are some options I'm not too keen on, but he tried to do what he could for the group and Clem. And Kenny wasn't a bro to me all the time but I think I sided with Lilly too many times and he decided he didn't like me, but to be honest I'm not surprised because he had a family to protect and he could of used my support more....
But anyway..... That idea doesn't really work for me.... Sorry
