The Brothers That Care Forgot

Rebekah, who was spent months away living a normal life with baby Hope, finds herself on the run when she realizes Esther found them. Convinced Finn and Kol would be powerful allies in his fight to take down Esther, Klaus sets a plan in motion to turn his brothers against their mother. Hayley is conflicted when she and Jackson stumble upon an ancient ritual which would get their werewolf packs out from under Esther's control, but it would require her to make a tremendous sacrifice. The ritual is about Hayley and Jackson getting married so their packs can have Hayley's hybrid powers. Rebekah is meeting with Elijah and is concerned when she notices something is off with him. Finally, Davina takes matters into her own hands by turning to dark magic so she can poison Klaus. Cami finds out Esther prepared her body for Rebekah to jump into it. Klaus talks with Rebekah about Elijah and then he and Hayley are going to visit their daughter.
