fans are about to get the happy ending they've been waiting eight years for – Dr. "Bones" Brennan and Seeley Booth are tying the knot in an episode airing on Fox on Oct. 21.
, who plays FBI Special Agent Booth, tells PEOPLE that he was "excited and happy" when he and Emily Deschanel
, 36, filmed the wedding scenes.
"I'm proud of the show getting to a place where we could really give back to the fans what they've been wanting for a while," he says. "It was a great moment for Emily and I to be in the shoes of the characters and go through that."
The 44-year-old, who's also a producer on Bones
, says they "went through a few drafts" when it came time to write the couple's vows.
"I don't think Emily went through as many vow drafts as I did," he says. "I wanted my vows to be somewhat of an experience of where we'd come from and where we are now today, so I gave them a bit of a history lesson on the altar – 'Look where we are, we've made it this far and do you remember back when we barely knew each other and were arguing?' So I wanted to play that aspect of it. It was a lot of fun."
