The seventh episode of 'Fallout' Season 2, titled 'The Handoff', presents multiple storylines. Maximus, portrayed by Aaron Moten, travels through the wasteland with The Ghoul, played by Walton Goggins. Meanwhile, Lucy, brought to life by Ella Purnell, is forced to sit with the uncomfortable truth that her father Hank may not be the hero she once believed he was. Then there's Stephanie Harper, played by Annabel O’Hagan, who is running through a frozen nightmare alongside Joan (Natasha Henstridge). They are fleeing a restricted zone near the Uranium City internment camp in Canada, bullets snapping at their heels. 

They make it under an airship only to be stopped by a soldier in power armor, who coldly orders them back to the camp. Before anything worse can happen, another figure rushes in and detonates explosives against the armored soldier. Then Stephanie wakes up. She’s back in the Vault, tangled in sheets, with Chet asleep beside her. As fragments of the dream keep surfacing, the audience learns it wasn't just a nightmare. It was a memory, as per Collider. The woman she was fleeing with had been shot and told Stephanie to head south, cross the border, find warmth, find life. 

She spoke about a coming flood, about holding onto whatever keeps you above water. She also gave a scary piece of advice, telling Stephanie that if she had to hurt people to survive, God wouldn't judge her, especially if she stopped seeing those people as people at all. Stephanie's journey south is cruel and fast. She kills a man for a can of pork and beans without hesitation. At the border, a customs guard calls her beautiful, and moments later, he's dead too. Back in Vault life, things look neat on the surface but rot underneath. It's the day before Stephanie and Chet's wedding, and what should be sweet turns sour fast.

When Chet asks why they're getting married, Stephanie snaps back that she's working. That's right. No romance. Later, Chet finds the sink clogged with what looks like Woody's glasses. When he asks about Woody, Stephanie calmly claims he's been sent to a leadership exchange program in Vault 31. Chet doesn't buy it. He breaks the glasses in half and shoves them back down the drain. Elsewhere, Overseer Betty Pearson (Leslie Uggams) is dealing with a Vault on the brink. Water rationing has gone from inconvenient to extreme. No showers. No toilet flushing.

In her office, Betty opens a hidden safe and pulls out a box of personal items. At Stephanie's request, she places the box between Vaults 32 and 33, though not without warning. Betty admits she has eyes on Stephanie and hints at everything she learned while Stephanie was "still under." Stephanie promises water will be restored, at least halfway, but offers no comfort beyond that. The wedding day arrives. The room fills. The vows begin. Stephanie says, "I do", without blinking. Chet does not. Instead, he chooses the worst and best possible moment to speak. 

He accuses Stephanie of planning to hurt everyone in the Vault. He brings up Woody's glasses. Then he drops the truth. Stephanie wasn't born in the Vault. She's over 200 years old. She's Canadian. He even has the ID to prove it. The witnesses from Vault 32 turn on her instantly. Stephanie runs, locks herself in her office, and the chants outside her door grow louder. The finale, Episode 8, is set to arrive Tuesday, February 3, according to Forbes. And honestly, it can't come fast enough.
