Synopsis for 'Service'

The synopsis for tonight's episode of "The Walking Dead" reveals that Alexandria will receive a visit. The sneak peek clips reveal that that individual is Negan. The villain has arrived earlier than anticipated and has brought several trucks and a large group of the Saviors. Negan is still not happy that Rick doesn't greet him with a smile.

Even though Negan said he would visit Alexandria in one week, he comes earlier.

This surprises Rick Grimes, but he has no choice but to open the gates. The Saviors all pour into the gated community, prepared to take their "share" from Alexandria.

Rick Grimes is no longer in charge

In one scene, Rick explains to his group that he is no longer in charge. He says that their leader is Negan. However, it appears that at least one person is determined to fight, even knowing what happened in the season 7 premiere.
