'Grantchester's Season 8 Trailer Hints at Will & Bonnie Marriage Struggles

Grantchester Season 7 ended with a surprise wedding after the Reverend William Davenport begged Bonnie Evans to stay in Grantchester and try to make a relationship work. Fans were startled at the sudden rush to the altar — though in the early 1960s, it was not as sudden as it felt to the modern eye. However, the wait for Season 8 has been one fans are looking forward to, with viewers finally getting a look at Bonnie and Will's relationship.

From the look of the trailer, life has changed for the better for Will, feeling the stability he's wanted now that he's married. However, something will disturb the tranquil domesticity, as the trailer shows Geordie once again having to push Will away from getting involved in a murder scene and suggests he may be a suspect. As for Geordie and Cathy, who separated for the second time in Season 7 over Georide's drinking, the two are still working their way back to each other, but their commitments to their careers may upset the delicate balance they've achieved.

As for the rest of the vicarage, Mrs. C and Jack are still doing well, but Leonard and Daniel are still dealing with the fallout from Leonard's outing and his changing role in the Grantchester community. Will everyone find their way through the drama? I guess we'll have to have faith.

Here's the trailer.
