In the Season 4 episode of "Good Bones" titled "Tiny Condo, Giant Upgrade," Karen Laine is seen fetching a pair of keys that daughter Mina accidentally dropped down the drain. As she bends to retrieve the keys, her back is briefly shown, and with it, a large tattoo (via House Beautiful).

While the scene is brief, fans got a good look at the colorful tattoo that seems to extend up her whole back and, according to House Beautiful, looks like a koi fish. While Karen did not discuss the tattoo at the time of the episode, she did mention it back in 2018, telling Marketplace Events (via House Beautiful) that "Most people are surprised to find that I have a tattoo that goes from the nape of my neck, covers my back, and extends down the backs of my thighs."

And while fans were shocked to see the tattoo, it isn't so out of character for the former attorney. In addition to the show, Karen has created her own nonprofit called Indy Home, which helps address homelessness in her area and can often be found doing more eclectic things like mushroom hunting, riding her motorcycle, and frequenting music festivals. Mina has called her mom a "hippy-dippy dreamer."
