Lexa is the adoptive mother of Madi, the Heda of the 12 clans. Years ago before Lexa was Madi’s mother she lost the love of her life Clarke due to Titus murdering her, Lexa promised Clarke on her deathbed that she wouldn’t revert to the closed off ruthless commander she used to be.
Josephine Lightbourne and her family and the rest of the Primes have been using Nightbloods/ those with royal blood as hosts for mind drives that allow for the Primes to transfer into and take over the bodies of others.
While paralyzed Lexa was made into the host of Josephine Lightbourne, the narcissistic sociopath genius who’s in love with Gaberial.
The Lightbournes however hadn’t accounted for Lexa having the Flame which contains the collective consciousnesses of the past commanders including Shediheda AKA the Dark Commander AKA Malachi. Lexa was greatly annoyed by the two evil psychopaths trying to control her body, though the Flame did allow for Lexa to maintain some semblance of control of her body even if Josephine took over at times.
Josephine whined Lexy let me drive! You’re so lame! I mean hot af but lame! I never had to share a body before, but hey you had to be an a$$! I can’t wait until I figure out how to kill you and all the other old creeps in my new body! Ugh, stop thinking about Clarke, wait no that doesn’t mean think about Costia your dead girlfriend 1.0! Just give me control Lexa! I’ll just take over sooner or later anyway! This is really inconvenient and annoying! Scarface doesn’t help!
The Shediheda scoffs Kill the b!tch Lexa! I’ve never been stuck in your head with such an immature whiney self absorbed brat before! And I’ve slaughtered children!
Josephine managed to use Lexa’s hand to flip the Shediheda off A$$hole
