'Teen Mom OG' Gets Messy When Catelynn Lowell Kicks Tyler's Sister Out of Their Old House and She Trashes It (Exclusive)

In TooFab's exclusive sneak peek of tonight's episode of "Teen Mom OG," Catelynn Lowell and husband Tyler Baltierra head back to their old house to check out the damage done by Tyler's sister, Amber.

Amber had been living in the couple's former home for some time, but after Catelynn and Tyler kicked her out, she completely trashed the place. The damage was so bad that neighbors ended up calling the cops, who were waiting for Catelynn and Tyler when they arrived.

"We had to post the house. There was a lot of complaints," a neighbor told the couple as they got out of their car.

"About what?" Catelynn asked. The neighbor pointed to a police officer standing nearby and said, "He can tell you everything."

"So we had a few -- obviously -- complaints about your house," one of the police officers told Tyler. "The main issue was the lawn and the front window. And right now, the water's turned off. So what we need you to do is mow the lawn, cover up that front window with plywood, just make the house more..."

"Yeah, trust me, that's why we're coming here right now -- to assess the damage," Tyler interrupted. Unsurprised by the whole thing, he told the police officer, "I kind of expected this. I heard the horror stories from people telling me."

When the cops left, Tyler and Catelynn went to the backyard to see just how much damage Amber did. It was a lot.

There was garbage everywhere, blankets on the ground, spare tires, empty coolers and plywood scattered throughout.

"What the f--k?!" Catelynn said as she looked around. Then Tyler spotted a burnt vacuum cleaner.

"You've gotta be kidding me right now," he said as he walked over to the dismembered and charred appliance.

As they headed inside to asses that damage, cameras panned to a notice that had been taped to the door. It was from the City of St. Clair. "Unsafe. Do not enter or occupy," the note read. "This home is deemed UNSAFE. It is a misdemeanor to occupy or allow a person or pet to occupy this premises and/or structure. There is a $500.00 fine and/or 90 days in for removing or defacing this notice."

Last week, Catelynn said that things were still "tense" between her and Tyler after her return from treatment, adding that she wasn't ready to dive into couple's counseling just yet.

Most of the episode, however, revolved around Tyler and his sister reuniting with their father. Butch was in rehab and was finally ready to make amends to his family members after completing six months of treatment.

"I thought it went really well," Tyler said after the amends process, which wasn't filmed. "Mine was way too short," he noted, adding that his father seemingly forgot about Tyler's "failed suicide attempt."

"After this, if he uses again, I think it would be required for my mental health to just give up," he told his wife and sister.

A second meeting between Butch, his kids and some counselors was filmed, where Butch said it made him feel "f--ked up" and "terrible" to "forget something that dramatic" of his own child.

Moving forward, Tyler told him to work on "consistency" and trying to make more of a "connection."

"Teen Mom OG" airs Monday nights on MTV.
