The Walking Dead season 7 episode 4 trailer: Negan's in charge in clip from 'Service'

'The remaining members of the group try to keep it together in Alexandria'

Season seven of The Walking Dead has been defined by one man: Negan. The villainous head basher has gone from bad to worse, torturing the minds of those who remain alive.

Episode four, titled ‘Service’, looks set to continue the morbid trend, once again centring on those who survived Negan’s attack, but this time over an extended period as the episode will last 90 minutes instead of 60.

Following the third episode’s conclusion, the trailer has been released showcasing Rick once again struggling with authority.

The synopses for the episode reads: “The remaining members of the group try to keep it together in Alexandria; they receive a sobering visit.”

However, it is perhaps episode five’s synopses that reveals more about ‘Service’. It reads: 'Saddled with grief and surrounded by enemies, members of the group try to find safety at the Hilltop before it's too late.’

Saddled with grief? Could another member of Rick’s gang be about to die? In the meantime, you can read about the five major talking points from episode three here.

The Walking Dead airs on Sunday nights at 9/8c on AMC in the US, and on Monday nights at 9pm on FOX in the UK.
