And while Avery captured viewers when she revealed she had converted to Islam and was determined to make things work with her Muslim love, Omar, fans are now on the edge of their seat when it comes to Tim's big secret.
Here's what you need to know about Tim and Jeniffer.
We first meet Tim, a successful North Carolina gun business owner, when he reveals he met a Colombian model, Jeniffer (that's two f's, one n), on a dating site and assumed off the bat that she was too attractive to be interested.
The two quickly fell in love. "Jeniffer is even prettier than I thought," he tells cameras. "So now I'm like 'Wow, this girl really might be out of my league.'" However, there is trouble in paradise when Jeniffer grows increasingly uncomfortable with the role that Tim's ex-fiancée plays in his life.
Both Tim and Jeniffer have young children from other partners. Jeniffer is the mother of almost 2-year-old Inti Violeta, and Tim co-parents Chloe, his ex Veronica's daughter, who's not biologically his. "We were together almost nine years and I raised Chloe since she was just over a year old," Tim writes on Twitter.
But Veronica and Tim are a bit too close of friends for Jeniffer's taste. "You want me to be friends with my exes too?" she asks, fuming. "And they call me and tell me, 'Did you eat?' What the f--k, is she your wife or what?"
Is Timothy from 90 Day Fiancé transgender? Looks like he's been hiding a big secret.
Preview clips for Season 3 of 90 Day Fiancé: Before the 90 Days show Tim and Jeniffer having a blowout argument that ends with Jeniffer walking away from their meal and throwing her drink in Tim's face. Fans on reddit and Twitter are assuming that Tim is trans and that's the secret he's keeping.
"EXACTLY what I was thinking," one redditor writes. "I don't have a problem with that, but if he IS trans, I think it's really sh--ty of him to develop a relationship without telling Jennifer first." "If that's the case," adds another, "I really fricking hope she already knows because I would not find it entertaining having Tim dragged on TV for being trans."
And while it would be highly problematic and transphobic for TLC to stretch that storyline out throughout the season, we have reason to highly doubt that Tim is trans at all. When one fan on Twitter said they were "so glad that 90 Day Fiancé cast their first FTM cast member," Tim replied, "What is FTM? Do I even want to know?"
The gun-touting Trump supporter has also been quite transphobic in his own accord on Instagram. "If you meet a girl that admits she's wrong, apologizes and changes her ways, dump her because that might be a man" reads a meme he posted to his page.
Others are thinking that the secret he's hiding has to do with the fact that he's recycling the engagement ring he'd previously given Veronica. To the dismay of many, the idea came from Veronica directly.
We shudder to see how Jeniffer will handle this proposal. Watch what unfolds when 90 Day Fiancé: Before the 90 Days airs Sunday at 8 p.m. on TLC.
