The Unlikely Love Story of Mac and Sweet Dee Reynolds on It's Always Sunny in Philadelphia

The Love Story of Mac and Tandy Reynolds

Mac Reynolds is one of the central characters on the hit FX show It's Always Sunny in Philadelphia. Portrayed by actor Rob McElhenney, Mac has been a fan favorite since the show's debut in 2005. While Mac is certainly a unique character with his own quirks and flaws, one relatable aspect is his romantic relationship with Tandy Reynolds.

Tandy Reynolds is Mac's long-time love interest and eventual wife on It's Always Sunny. Played by actress Kaitlin Olson, Tandy (who goes by Sweet Dee) is the sister of Mac's best friend Dennis. Though their relationship has had its ups and downs over the show's 15 seasons, Mac and Sweet Dee remain one of the most iconic TV couples.

The Origin of Mac and Sweet Dee's Relationship

When It's Always Sunny first premiered on FX in 2005, Mac and Sweet Dee were not romantically involved. In fact, early seasons focused more on the dysfunction of the entire gang of friends - Mac, Dennis, Charlie, Sweet Dee, and Frank. However, sparks began flying for Mac and Sweet Dee in season 3.

In the season 3 episode "Mac is a Serial Killer," Sweet Dee kisses Mac unexpectedly. This plants the seed for their future relationship. As the series progressed, Mac and Sweet Dee shared more intimate moments, including a marriage proposal from Mac in season 7. Though initially reluctant, Sweet Dee eventually accepts.

The evolution of Mac and Sweet Dee's relationship coincided with Rob McElhenney and Kaitlin Olson developing a real-life romance off-screen. The actors married in 2008 and now have two sons together. Their natural chemistry clearly influenced Mac and Sweet Dee's slow burn courtship.

Mac's Long-Harbored Feelings for Sweet Dee

Even before they began dating, it was hinted that Mac always had a crush on Sweet Dee. As children, Mac was enamored with Dennis' twin sister. He even carried around her braces after they were removed as a childish token of his affection.

As adults, Mac continued to show an interest in Sweet Dee, though she consistently rebuffed his advances. However, after sharing an ecstasy-fueled kiss in season 3, Dee began to develop feelings for Mac in return. Their friendship gradually blossomed into romance.

Mac's devotion to Sweet Dee, despite her flaws and rejection, is a testament to his patience and persistence. His long-harbored feelings were finally reciprocated after many years. For fans watching their slow burn courtship, it was sweet payoff.

Mac's Grand Romantic Gestures

As his feelings for Sweet Dee grew, Mac began making huge romantic gestures to prove his love. These over-the-top displays often landed flat or ended in disaster, but showed Mac's sincerity and commitment.

In the season 7 episode "The Storm of the Century," Mac proposed to Sweet Dee in an elaborate Valentine's Day setup. Though Sweet Dee initially declined, she was eventually won over by Mac re-proposing in a follow-up gesture: lighting fireworks spelling "Marry Me Sweet Dee" off of a building.

Mac's proposal was not the first grand gesture for Sweet Dee. He also serenaded her with a rendition of Joe Cocker's "You Are So Beautiful" in season 5, though it failed to woo her. And in season 9, Mac performed a sexually explicit hip-hop dance for Sweet Dee, which only resulted in making her uncomfortable.

Though his methods were unconventional, Mac's attempts highlighted his willingness to make himself vulnerable for Sweet Dee. His grand gestures revealed his deep feelings for her.

Mac and Sweet Dee's Wedding

After a long courtship, Mac and Sweet Dee finally tied the knot in season 9. Their Irish Catholic wedding was appropriately chaotic and dysfunctional. Mack struggled with writing personal vows, while Sweet Dee's family heirloom wedding dress was unflattering.

However, after a series of mishaps, the wedding eventually came together. Mac and Sweet Dee read their handwritten vows, and sealed their marriage with a kiss. The ceremony encapsulated their unconventional relationship - imperfect, but coming from a place of genuine love.

The wedding episode also revealed Dee was pregnant, unbeknownst to Mac. This surprise pregnancy mirrored Kaitlin Olson's real-life pregnancy at the time. However, it led to hilarious scenes where Mac had to quickly prepare for imminent fatherhood.

After 9 seasons of build up, Mac and Sweet Dee's wedding marked an important milestone in their relationship. And it paved the way for the next phase of their romance: parenthood.

Mac and Sweet Dee Settle into Domestic Life

After their wedding and the birth of their baby, Mac and Sweet Dee did their best to settle into domestic life. Of course, this transition was not without hiccups and comedy.

Much of the humor stemmed from Mac struggling to understand fatherhood and the responsibilities of married life. Like when he became fixated on who the baby resembles, despite them not being biologically related. Or tried inventing dangerous activities for infants to help his son get "swole."

Meanwhile, Dee took to motherhood more naturally, but also maintained her signature narcissism and vanity. She was insistent the baby always be referred to as "Dee's baby." Nevertheless, they both made efforts to embrace their new roles, in their own dysfunctional way.

Seeing Mac and Sweet Dee attempt to create a family together gave both characters growth and added dimension. Underneath the jokes, was an exploration what really makes a family - not just biology, but love.
