The final Reality Fracture episode resolves the still-intertwined Multiverses after Jace's death. Tam uses the expanded telepathy carried in Jace's spark to contact Emrakul, who leaves Innistrad's moon and consumes the artificial Echoverse while preserving the original Multiverse.
Jace's recorded message confirms that Tam was built as his fail-safe and intended heir. His spark completes her with the missing parts of his mind, after which Tam planeswalks to Strixhaven and later approaches Vraska to continue Jace's work. The finale therefore establishes both the destruction of the Echoverse and a new Planeswalker carrying Jace's legacy.
