Leo, Paige, and Phoebe go to Alexi's lair per advice from Cole. Unfortunately, they find her dead with one of Rennek's arrows sticking out of her chest. Alexi appears to the group from inside of her mirror, having infused a piece of herself within the mirror in order to give the Charmed Ones information on how to deal with Rennek. Alexi tells Leo that the key to the future lies in his past. Following the battle, we find Gideon and Leo outside of the Manor, Gideon telling him that because he defeated Rennek, the Elders feel he's ready to deal with these difficult charges.
