is it just me, or did the last one make no sense; how the hell did it take shane and rick half a day to walk close enough to the house

where carl could come out after hearing a gunshot? also, how the hell did Shane turn into a Walker in general, not to mention so quickly?

or is it a dream sequence maybe?

It can take minutes to hours before a person turns into a zombie, it varies.

not just that; he didnt even get bit!

They might elaborate on that next episode, but I already know the reason. If you go back to a couple episodes ago, there were two...

...deputies that were zombies and didn't have any bites or marks on them either.

damn, forgot about that. thanks

I thought he was some sort of zombie creation machine when he killed that kid behind a tree who then became a biteless zombie.

it's part of the universe, in the comics it's the same way, Rick even goes back to were Shane is buried to make sure

once you die you become a zombie, doesn't matter how you die

ahhh i did not know that, but yeah, it was kinda crazy; I still think carl being right there was a little too convenient

Well Carl never fucking listens, so I didn't find that unusual.
