Walking dead seems to have hidden Easter eggs this season,here are a few
"Not only will that bullet play a huge role in bringing down the show's new villain but it was symbolic of the end of civilization.
See, late in Season 6, Rick Grimes explained the broken window fallacy, which means keeping windows in tact is symbolic of keeping society and civilized culture in tact. As Negan comes marching into Alexandria, representing oppression and chaos for the citizens of the Safe-Zone, he shattered not only their windows but also their civilization.
It's a fun and impressive little nod to previous moments on the series.
Earlier this year, Negan reflected Merle Dixon's line to Glenn Rhee. In 7x03, Negan swung his bat at Daryl and told him, "You don't scare easy," upon Daryl's lack of flinching. In episode 3x07, Daryl's brother Merle said the same thing to Glenn when he was being held hostage at Woodbury."
