this thread again...
EVERY picture in that trailer either shows things differently than how they happened, or shows things that never even happened at all.
From my other post on this subject:
The picture is practically covered in blood, it wasn't in the game.
Lee, Christa and Kenny in the sewer together, no scenes in the game showed that.
Lee smashing the babysitter further back with the hammer and the back door closed, that happened differently.
The suicide scene seems to be in the same woods that we saw in the earlier episodes, they're now in a city.
The group camping in front of the train at night, that never happened.
