Henrietta "Hen" Wilson (Aisha Hinds) is a competent and dedicated first responder with a great family and a strong head on her shoulders, making her a fan-favorite character. She is even going to medical school, on top of being a member of Station 118. While Hen is often the most grounded character, she is nonetheless a flawed one. Hen and Karen are on pretty solid footing nowadays, but this was not always the case. If you started watching "9-1-1" after Season 1, you might be shocked to learn that Hen once cheated on her wife, Karen (Tracie Thoms).
We first learn of their conflict in the fifth episode of Season 1, when Hen's ex-girlfriend Eva (Abby Brammell), the biological mother of her son, Denny, asks for help with her parole, upsetting Karen. Later, in "Full Moon (Creepy AF)," Hen sleeps with a recently released Eva, which Eva later attempts to use as leverage in her attempts to regain her parental rights of Denny. When Karen finds out about the infidelity, she takes Denny and splits. Eva never gets custody (she goes back to prison in Season 2), and Hen and Karen were, thankfully, able to work through the betrayal. Eva made a brief return in Season 5 to say goodbye before moving to Oregon, in an episode where Karen confronted her face to face.
