Oh Petra, how we're going to miss you. While seeing her have financial success — expanding the Marbella brand overseas — is great, it's the fact she gets her own happy ending with JR that makes her story extra sweet.
Following a heartfelt toast at Jane's rehearsal dinner — "I wish you all the happiness in the world, which is a really weird feeling because I don't usually wish happiness on other people" — she is one of the first people at the ceremony the next day since the rest of the wedding party is running late on the bus. That ends up being perfect since she's able to spot JR sneaking into the back.
Petra runs down the aisle and all but leaps into JR's arms, and the pair confess their love for one another and share a passionate kiss. It's a beautiful moment, and no one deserves it more than Petra.
