Speak now or forever hold your peace.
Hopefully you've already picked out your gown and have bought a gift because we're about to attend another wedding on Reign!
Greer (Celina Sinden) is set to finally say "I do" to Lord Castleroy (Michael Therriault) on the CW hit this Thursday, right in front of her former love, Leith (Jonathan Keltz). But will the baker-turned-King Francis' (Toby Regbo) BFF pull a Taylor Swift and object during the wedding?! (Hey, they both do love to bake!)
We've got your exclusive first look at Greer and Lord Castleroy's wedding in the sneak peek above...
But Leith might have good reason, aside from his feelings for Greer, to object as he and Bash (Torrance Coombs) will discover a surprising secret about Castleroy that could destroy his union with Mary's (Adelaide Kane) lady-in-waiting during their investigation of the Protestants and Catholics' latest bloody showdown.
Still, even if Greer and Castleroy do end up tying the knot, all hope is not lost for Leith fans as showrunner Laurie McCarthy told us we will be seeing an open marriage this season.
And in case you aren't watching Reign just yet, Buffy the Vampire Slayer and Avengers mastermind Joss Whedon has recently joined the show's fan club. "No, YOU'RE binge-watching REIGN on a Saturday night," he tweeted. "No. No, it's not you. This is who I am. #GOWNS #history #Avonlea"
Reign airs Thursdays at 9 p.m. on The CW.
