After hearing the shocking news about Mia's arrest, Married at First Sight experts -- psychologist Dr. Jessica Griffin, sociologist Dr. Pepper Schwartz, and marriage counselor Pastor Calvin Roberson -- flew to Dallas as soon as possible to sit down with Tristan and Mia in person.
"Pastor Cal, why was it so important to you guys... to physically be with Tristan and Mia?" Jamie Otis asked the expert during Tuesday night's episode of Married at First Sight: Unfiltered.
"We were going to fly in but then Tristan and Mia said they wanted to spend some time together. So what we did is, we waited," Pastor Cal began.
Mia was detained in a Texas airport while she and Tristan were traveling to Cancun, Mexico for their honeymoon. Mia was pulled away for questioning and spent two days in custody due to a warrant that had been issued for her arrest back in February.
Once Mia was released without bail and returned home to her husband in Dallas, Tristan asked whether the stalking claims he had read in the warrant were true and if she knew or had any type of relationship with the accuser.
Mia denied knowing her accuser and insisted all claims against her, including unauthorized use of a man's credit card, were "100 percent false" and someone had stolen her identity.
Although Mia's story didn't really make sense, Tristan had no reason not to trust his new wife, so he hugged his wife and dropped the topic.
However, Mia "came clean" to Tristan off-camera days later that she did, in fact, have a brief relationship with the man who had filed the arrest warrant.
"When we found out that she hadn't told the entire truth, that there had been some dishonesty early in the relationship -- which is never, ever good -- we felt that it was important for us to go in immediately and sort of walk them through this process so that they could use this to heal," Pastor Cal explained on Unfiltered.
"This doesn't sound great, but it's much easier to be untruthful to someone you don't really know than to tell the truth to someone you're really committed to. And as the relationship grew, she felt she had to come out with more of the truth."

The arrest warrant had been issued after Mia's alleged ex-boyfriend, Jared Evans, claimed she had stalked him on multiple occasions in the 13 months that followed their December 2016 break-up and also made an unauthorized purchase of an Apple iPhone on his credit card a year after their split.
Tristan was upset when he realized Mia had lied to him and betrayed him, but he decided to stand by his wife when she needed him most and continue to make their marriage work.
"It would be tough to completely forget. You know, I think, like Danielle said, the hardest part is not what they went through, it's the lack of honesty, because then you just question everything," Dave admitted.
When Jamie asked Calvin if he believes Mia and Tristan could genuinely get past this in their marriage, the pastor replied, "Yeah, I believe so -- if they can be completely honest and completely open and she has to put everything on the table."
He continued, "She has to spill her guts and tell everything about that situation. If they can do that and that's what's being done now, they can use that. And it can work. So, time will tell."
