20. Gemma Exposes Tara's Tattoo
Season 1, Episode 1: "Pilot"
The very first Sons of Anarchy trots out most of the drama's most important players — including Tara Knowles (Mad Men's Maggie Siff), an old high school girlfriend of Jax's who'd rejected the biker life and recently returned to Charming to work in the pediatric ward of the local hospital. Ever the club's house mother, Gemma tends to takes every real and imagined rejection of the Sons as a personal attack. So when the two of them run into each other, Jax's mom lifts up the back of the doctor's shirt, exposing Tara's biker tattoo to remind the young woman of who she used to be. Here, in one brief moment, is the introduction of one of SOA's big themes: Some scars and stains are permanent.
