Bridgerton Season 4, Part 2 picks up in the wake of Benedict's disastrous "proposal," and from the looks of the trailer, there's a lot of angsty yearning from both parties as Sophie takes some time to weigh her choices. Ben and Sophie don't go completely no-contact though, as the trailer also showcases a fair share of steamy scenes between the star-crossed lovers. On top of seeing how this delicious Cinderella story ends, Bridgerton Season 4, Part 2 will also see the return of Kate (Simone Ashley) and Anthony (Jonathan Bailey), as well as more sumptuous string covers of pop hits. — B.E.
