Samantha Hanratty of the Yellowjackets knows what makes Misty so dangerous

In episode 5, "Two Truths and a Lie", best friends Misty and Crystal (Nuha Jes Izman) head to a nearby precipice to empty the camp's scavenge bucket, which for some known reason solely from Misty, prompts her to divulge the shameful secret she's been keeping bottled up since the show's second episode: that she destroyed the black box of the downed plane. When Crystal gets solemn and nervously informs Misty that she needs to tell the other girls, it's like you can see a switch go off in Misty's eyes. She crosses over, briefly inhabiting the state she occupies 100% of the time as an adult as she straightens up, walks over to Crystal, and threatens to shut her up with a vow of retributive murder. Then Crystal crumbles to her death.

In her interview with ET, Hanratty focused on the brief moments between Misty's confession and transformation, during which she goes through a list of intense emotions: panic, betrayal, sadness, anger. "Why she's so surprised by Crystal's reaction is because it wasn't really something she was nervous about saying," Hanratty ventured. "I don't think she ever saw it coming to this point." Hanratty nails the quality of Misty that provides a dividing line between her teenage and adult forms. As unhinged as she is, as intimidating as she is, Misty always seems to operate from a place of pure innocence, even ignorance, towards her own motives.

"I think that's part of what makes Misty so dangerous. She doesn't really take responsibility for what she does," Hanratty continued, pointing out the non-consensual dosage of mushrooms from all of her teammates. "She doesn't admit things, which makes her so scary."
