WATCH: Jesse Tyler Ferguson Dishes on Historic Modern Family Wedding

Warning: minor spoilers ahead.

Part 1 of Modern Family's two-part season 5 finale ended in a cliff-hanger last night with the wedding of gay couple Cam and Mitch apparently in jeopardy. However, the show's out star Jesse Tyler Ferguson spoke with The Wall Street Journal today to assure fans that, despite part 1's drama, the couple would be saying "I do" by the end of next week's episode.

"It's going to happen," Ferguson told the WSJ. "You're going to have to wait another week, but it's going to happen."

When asked about Modern Family's possible contribution to America's evolving attitude on marriage equality, the four-time Emmy nominee said he believes the show has had an undeniable impact. "It's certainly hard to pat ourselves on the back because we are just doing a comedy, but I can't ignore that the show has social ramifications and I think there's something really lovely about the way our writers have introduced Cam and Mitch to America," Ferguson said. "For a lot of people they might be the first gay couple that they know, or at least that they know are definitely gay, and I think it presents them in a very safe way. We sort of call our show the Trojan horse [because] we sneak in people's rooms and before they know it they love us."

As the cofounder of Tie the Knot, a foundation that sells custom bow ties and donates all proceeds to various organizations fighting for marriage equality and LGBT civil rights in general, Ferguson also took a moment to offer wedding style tips for grooms.

In a 2013 interview with The Advocate, Ferguson was quick to credit his husband, Justin Mikita, with the concept for Tie the Knot and awaking his own passion to fight for LGBT civil rights on a larger scale. "Justin came up with the idea," he said. "I've definitely become more of an advocate, philanthropist, and do-gooder because of him. He has really ignited the civil rights passion within me."
