Season four of “The Profit” has been nothing short of explosive. Marcus Lemonis, self-made millionaire and entrepreneur, works to help struggling businesses succeed once again using his famous People/Process/Product principle, explaining that at leats two need to work in favor of the business in order for it to succeed.

Each episode brings its own set of difficulties, including drama between owners (who sometimes happen to be family members), owners who are unwilling to change things for the better of their company and, of course, those that are reluctant to allow Lemonis to be 100 percent in charge. Some tensions result in a business owner losing a deal, while others go on to prosper.

Here are eight of this season’s most explosive moments yet:

1. Tea2Go

In last week’s episode, Lemonis expresses his frustration to the vice president, who also happens to be the owner’s son, who didn’t show up to a meeting with the franchises. During the International Franchise Expo, Lemonis confronts Taylor Logan, saying, “I don’t know that you’re cut to work here. I’m pissed right now. I’m record pissed. And I am not gonna f*ck around.” He goes on to say he could be fired if he doesn’t get his act together, adding, “This sh*t isn’t going to fly with me.” In the end, however, Lemonis works with Logan on a new tea/spice shop called American Tea & Spice Shop and tells him that the company will pay for him to finish his education.

2. Pacific Hospitality

Tensions boil over when Lemonis says that he wants Ana, the soon-to-be head designer of both Pacific Hospitality and Grafton Furniture, to lead a design process. That does not go over well with Steve, Grafton Furniture’s owner and designer. Steve boasts his experience and says he’s unwilling to let go. Lemonis even calls out how “pissed” he looks. Eventually, they agree to work on separate designs in a competition format, which Ana goes on to win.

3. Honest Foods

What seems innocent at first quickly turns sour when Honest Foods owner Tad is informed that an order needs to be moved up by half an hour. The sudden pressure causes him to switch his seemingly calm demeanor to a more frustrated attitude. He begins yelling at his employees to “hustle” and his employees eventually warn Lemonis that there could be a mutiny if things don’t change. Tad eventually changes his attitude, however, and Honest Foods makes a comeback by the end of the episode.

4. Flex Watches

Lemonis becomes frustrated when charity watch company Flex Watches puts together a display case that he says “looks like a high school art project.” He tells them they can’t rush things if they want quality and advises them to “slow the f*ck down.” By the end of the episode, they debut a colorful new display case that conveys their mission, get back to their storytelling roots and have a complete breakthrough.

5. The Soup Market

Who’s Grace? That’s the central question Lemonis seeks to answer in The Soup Market‘s episode. Turns out, when Grace finally emerges, that she is the director of operations, who the owner Dave has tried to keep away from the business. Why? Dave had previously admitted to his wife that he had feelings for Grace, which caused trust issues to emerge in their relationship. Dave had then requested that Grace remain “invisible,” which she says is interfering with her livelihood. After leaving the Milwaukee-based company, Lemonis receives a call from Grace, who tells him that she was fired and had 911 called on her by Dave after refusing to leave. Tensions fully boil over when Grace says that she had previously filed an EEOC complaint for sexual harassment against Dave. They fail to resolve their issues in the end and Lemonis walks away from the deal.

6. DiLascia

If there’s one thing that you learn from watching “The Profit,” it’s that Lemonis can’t stand when employees don’t have their numbers together. He becomes frustrated that there is no data to support the numbers at DiLascia and that there is no process in place to launch products. Eventually, they implement a new process and the clothing brand successfully narrows its focus.

7. Murchison-Hume

In what has probably been the most explosive episode so far this season, the owner of Murchison-Hume, Max, becomes frustrated when Lemonis challenges the company’s branding. She storms out and says, “Bye bye, pretty little fancy labels.” She calls the decision “wrong” and causes much more drama throughout the entire episode. Lemonis finds out that Max had shelf space in a store staged so it looked like they had better positioning, she accuses Lemonis of lying to her and he eventually tells her to “cut the sh*t.” By the end of the episode, given her “flippant attitude,” Lemonis walks away from the deal.

8. Bowery Kitchen Supplies

In this sneak peek clip from tonight’s episode, Lemonis is visibly frustrated with the owner, given that he hasn’t been putting in his fair share of the work. The owner says, “It’s August, I always go away in August. I went to see my mother and I went to see my girlfriend, which I always do in August—the slowest part of the year.” The small tiff then escalates into a full-on argument, resulting in Lemonis telling him how much money he has put into the company, far more than he originally intended.
