How different would it be.
How different would it be if, say instead of Kenny surviving a herd of walkers for no apparent reason, that at the lodge we met Lilly instead. How different do you think Season 2 would've went? Baring in mind, Clem actually had interaction with Lilly in Season 1. She even has her hair pinned back with the bands Lilly gave her.
And. What would've been better. The Russian stand off in Episode 4. Or 400 day characters catching up to the group at the end of Episode 4 and replacing the Russians? Perhaps, with the 400 day people replacing them, the Russians could come to Clem's group defence depending on how you treated Arvo.
