Thomas visits Marcus's basement and sees parallels between their exiled lives. He lays out the four Undoing requirements: the coins, Bridge blood, St. Bernardine's hellmouth, and the Lance of Longinus — currently held by Torretti, the man who killed Marcus's father. The impossible task crystallizes.
Marcus infiltrates the Temple of Ascension and meets Michael face-to-face. Michael reveals his strategic plan while showing emotional depth through a childhood photograph. He gives Marcus complete intelligence as a gambit, betting family connection will create hesitation.
