[Warning: The following contains MAJOR spoilers for The Cleaning Lady Season 4 Episode 9, “Hearts on Fire.”]

The Cleaning Lady just referenced one of the most iconic episodes of Grey’s Anatomy. Season 4 Episode 9, “Hearts on Fire,” saw an immigrant woman kidnapped and put under anesthesia by Cowboy Hat (Brian Norris) and his cronies, who then dropped her unconscious body at the hospital where Thony (Élodie Yung) works. A gruesomely shoddy surgery was performed on the woman while she was under, as evidenced by a giant T-shaped incision running up and down her abdomen with thick and bloody stitches. The woman was suffering from a bad infection as a result, but Thony noticed something so much worse: There was a bomb implanted inside of her.
