Twice the Grieving, Double the Loss - S1-E7
Revealing mistake: During the flashback, when Chucky is putting on his coat to leave the apartment, if you look very closely, you can just barely see the outline of either a very tight sports bra, or chest-binder top under Chucky's white shirt. (The white shirt is ever-so-slightly translucent in the light.) Since Chucky is played by a woman in these scenes, this garment would be used to help hide her breasts and give her a flatter, male-looking chest.
