I thought of it too. Even when they first started walking across the roof I had a feeling they would fall through.

 

I just knew that the roof would fall in as soon as I saw the water

 

Sure was a good and convenient thing there were no walkers lurking in there where they fell.

 

I totally thought of that episode. Water on the roof, the roof is going to cave in.

 

I didn't think about the Bob episode, but as soon as I saw them climbing up onto the roof, I said, "They're going to fall through the roof." That was so predictable.

 

That bothered me...
And as soon as they got done falling they're down there laughing...
Like they didn't check for any walkers, like you said good thing there weren't any (of course for the purpose of the show there weren't lol).

 

There were several things in this episode that went back to previous episodes. Falling through the roof, getting trapped in the car like Rick in the tank, walkers eating the deer like the horse by the tank, Rick looking like was swarmed by walkers and then crawling out like Glenn's dumpster dive.
