On a lighter note, this was the first walker we ever saw on TWD, the Teddy Bear Girl:
On S1E1 Rick sees her bending down and catching that teddy bear and mistakes her for a living girl. He calls her, she turns around, he sees she's a walker and shoots her on the head. And then we see the opening credits for the first time.
S1 also has Morgan's dead wife trying to turn a doorknob so she can enter the family home (and eventually she succeeds as we learn a few seasons later). Oh, and there's that walker who tries to break the glass door on episode 2 or 3.
Walkers climbed stairs all the way up to the rooftop where Merle was handcuffed:
They also used to run pretty fast (not a fast as the French ones, but still) until S3, if I'm not mistaken. Sophia and Rick were chased by two walkers after all on S2. After the farm they started to get slower until the point they are now - which is pretty harmless and stupid.
Like I don't think TF could have walked so slowly on S5 if those walkers behind them were like the S1/S2 walkers:
So I guess what I'm saying is that this...?
Not really breaking news, Aaron my beloved. Sorry.
