The mother-daughter relationship between the tribrid doppelgänger, Alexandria Gilbert and the tribrid, Hope Mikaelson.
Hope was conceived Bring It On and was born in From a Cradle to a Grave in St. Anne's Church. Alex is very loving and protective towards her daughter. To protect her from various enemies, such as the French Quarter Coven and the Guerrera Family, she placed Hope under her aunt Rebekah Mikaelson's care for a few months.
They are reunited in The Map of Moments where Alex is finally able to enjoy motherhood. Alex leaves again to make an alliance with her pack and to protect Hope further, so Hope was left with Elijah and Camille O'Connell to look after her.
Elijah and Cami brought home Hope to the compound in I Love You, Goodbye. Alex married Jackson in order to bind his pack to Alex for Hope's protection.
Alex and Hope lived together in the compound until later on, when Alex decided to leave New Orleans with Hope and her pack, following her new husband's advice that removing the Mikaelsons from Hope's life would be the best thing for them.
Klaus found them and cursed the Crescent Wolf Pack including Alex and took back Hope from Alex.
For months Alex and Hope only saw each other once a month for a few hours on a full moon, though when the curse was broken in You Hung The Moon, Alex took Hope and moved out with her and Jackson.
After the prophecy came true and the Mikaelson family fell, Alex left New Orleans with Hope to find cures for the family and end up in Mystic Falls for four years. They lived quietly together for a year in a country house, until Alex woke the Mikaelson's.
They are referred to as "Alehope" by fans.
