How on Earth did she escape those walkers without getting bit, there were at least 6 right on top of her
Spoiler:
It's always been one of the sillier bits of plot armour. A minor character encounters one walker and gets a chunk instantly taken out of them... or a character can be totally swamped and fighting them off from literally on top of them and not one little tooth gets through . Also just the fact that they know one bite is a death sentence but they don't wear things like chain or tough leather armour as standard, even just on their arms and legs, when that would definitely stop a walker bite (and is clearly the purpose of the shiny Commonwealth armour). Actually reminded me a bit of Glen scrambling under the dumpster without so much as a scratch.
The other thing that's been bugging me is that it was clear at the end of the last season that Lydia has the effortless ability to "walk with the dead" as a whisperer, and even Negan had learned it relatively quickly (I think in the space of a few months?). Most characters have to use the "guts trick" which we know they don't use often because of the risk (like poor Gabe lol) ... but A) they haven't thought to have them teach this skill to others and B) we've now seen both of them encounter walkers and NOT use that skill . Instead of Lydia fighting the large group in the warehouse head on like the others, they should have had her "fade back" into the walkers and start taking them out stealthily from the back... like her "special ability" if she was a game character or something... but also why couldn't Negan do the same in the tunnels? In theory, neither of those characters should be at risk from walkers, we've seen them walking with hundreds of them. . Maybe Negan does need to be "smelly" to do it. But it was made pretty clear that it's easy-peasy for Lydia.
