Mare of Easttown: Checking in With the Most Popular Theories About Who Killed Erin

Erin's best friend Jess seems to be privy to all of her secrets, including her love and personal life. While she's shaken to her core at having lost her friend, she's ever so hesitant to disclose all the information she may hold regarding the case. She eventually opens up about Dylan not being the real father and Erin's plans to make money off registering an account on the escort website under a pseudonym to pay for her son's ear surgery. Even now, it's visible in her eyes and her body language that she knows more than she's letting on. But the odds of her killing her friend are pretty slim.
