It’s been a long time coming, but the This Is Us season five finale is finally here. However, the series’ final episode, which aired in the US last night and will drop on Amazon Prime in the UK tomorrow, came as a bit of a shock to viewers.

As you’ll likely know if you’re caught up with season five so far, one of the biggest stories leading up to the finale has been Kevin’s (Justin Hartley) relationship with Madison (Caitlin Thompson). And while the couple’s wedding – and their decision not to tie the knot – certainly played a part in the final episode, it wasn’t the biggest wedding-related revelation that came to light.

Indeed, the most shocking moment came in the form of a flashforward scene, which depicted Kevin rehearsing a wedding speech. Although, at first, it seemed like this speech might be for his wedding to Madison, when the flashforward scene resurfaced at the end of the episode (after Kevin and Madison have called things off) it’s clear this isn’t the case.
