T.K. and Carlos proudly parade their dapper tuxedos before Owen, Mateo, and Nancy, an exhibition that borders on an emotional spectacle. Amidst unanimous praise for the tailored elegance, Owen's sentiments diverge slightly, with a twinge of disapproval reserved for the pocket squares. The groom-to-be's companions propose a swap, but Owen divulges his true grievance: it's not the squares, but the overall color scheme that fails to resonate. He aspirations soar beyond mere trendiness, vowing for a wedding that transcends the ordinary, shunning the label of "cool" in favor of something divine. As he paints a picture of an unforgettable affair, Carlos humorously interjects, noting that one guest is already causing quite a stir.
Later, Carlos graces the firehouse with an armful of tacos, eliciting cheers from the entire crew, their appetites undeniably more piqued by the food than the visitor. Owen breaks the festive mood with news of a wedding cake tasting at the residence the following day, introducing a surprise twist—a gluten-free, sugar-free, dairy-free alternative to the conventional white cake that Carlos's family bakery had impeccably crafted for his sisters' quinceañeras. Owen argues that sugar highs lead to abrupt lows, sucking the life out of celebrations.
In Owen's wake, the team confides in each other about his increasingly apparent need for control, likening him to a man intoxicated with authority. Judd suggests a straightforward conversation, recalling a failed attempt with Grace's father that resulted in a prolonged silence. T.K. muses on the thought, acknowledging the rare intensity of his father's enthusiasm. Carlos, however, is hesitant to mar the start of his relationship with his future son-in-law by issuing a "back off" notice. Amidst their witty banter, Judd, Paul, Mateo, and Nancy's jokes hit home, and Carlos realizes he knows just the person capable of standing up to Owen without causing irreparable harm.
In a fashion reminiscent of The Godfather's iconic confrontations, Andrea Reyes confronts her son and future son-in-law, both offering apologies for their inadvertent exclusion. Carlos explains their desire to craft a wedding uniquely theirs, yet their meticulous plans have faltered ever since Owen's "descent into madness," as T.K. succinctly puts it. Hoping Andrea could rein in her husband, she wisely notes that maintaining harmonious in-law relations is paramount, declining to intervene in Owen's quest for control.
When the trio arrives at Owen's for the cake tasting, he enthusiastically pitches the idea of a vegan cake. A blind taste test ensues, and to everyone's surprise, the vegan option triumphantly steals the show. As Owen and Andrea indulge in discussions about cakes and floral arrangements, T.K. and Carlos realize their carefully laid plans have spectacularly backfired, with their parents now united in their extravagance.
Inspecting the floral displays, T.K. and Carlos find them overly grandiose, contrary to their original vision. However, Owen and Andrea eagerly advocate for even grander designs, offering to foot the bill. When diplomacy fails, T.K. finally asserts himself, terminating his father's services, while Carlos follows suit with his mother.
Back at the house, Owen and Andrea share a slice of the traditional cake, their conversation turning to their sons. Andrea opens up, confessing her confusion and inaction when Carlos came out. Her deepest regret is her inaction, and Owen reassures her of her motherly prowess. Empowered by her honesty, Andrea inquires about Owen's excessive wedding preparations.
Owen seeks out T.K., who is alone in the loft after Carlos's departure with Andrea. Admitting to a touch of overenthusiasm in planning, T.K. dismisses it as mere "slight" exaggeration, the irony not lost on either of them.
Owen candidly confessed that his leap into the unknown was fueled by the poignant realization that it might mark the final occasion where T.K. would solely rely on him. Nevertheless, T.K. fervently asserted that his dependence on Owen was far from over, highlighting Owen's remarkable role as a father, inspiring aspirations within him to emulate that same greatness one day. He affirmed that Owen's wisdom, guidance, and unwavering friendship would continue to be invaluable as he embarked on his own journey of fatherhood, with Owen ever by his side as his dearest confidant.
