We already know Malivore is a place that is freeing all the ancient monsters and the knife was one of the keys to the three locks - but what if Landon Kirby is the last lock, the one that's keeping it all contained? 

CW's 'Legacies' just wrapped up its mid-season finale leaving us wondering what really is Malivore and now that the knife is destroyed, what fate will befall our supernatural Avengers? Fan theories suggest that even though Hope Mikaelson found no trace of magical lineage in knife thief and Hope's love interest Kirby, there's a chance that he may be magical after all. 

The show has made it clear to us that Landon has one supernatural ability that allows him to resist compulsion and Hope's tests told us that he's not supernatural. This is why his complete lack of magical trace is strange - even humans, typically, have traces of magic in them passed down through thousands of generations in 'The Originals/The Vampire Diaries' universe. Compulsion is the ability of Immortals, Original Vampires, Vampires and Hybrids to control the mind of someone else by just looking into their eyes. The only people Immortals cannot compel are Hunters and Passengers. 

A Redditor suggested that the situation in 'Legacies' was like a flashback to Dawn Summers from 'Buffy the Vampire Slayer'. In 'Buffy', in order to safeguard Dawn, the monks who were protecting her had managed to magically modify everyone's memories in such a way that they didn't question her sudden appearance.

It was all done in order to protect her identity when she started hunting for the supernaturals. We know Landon grew up with Raphael, the werewolf and he goes out of his way to protect Landon. However, so far, all Landon has done is lied to him. Their bond between brothers is missing, to say the least. There's a possibility that Landon is like Dawn - and whoever helped shut Malivore in the first place is the one who planted it into Landon's memory that he is human. 

This theory also fits in with the story arc of Landon and his mother - she may have sent him away to protect him. If she's involved with Malivore and its creation and sealing, which she most probably is, then it would mean that she's met her share of monsters too.

Landon may have been a baby at the time and she could have sought the help of the same possible witches from a fan theory who helped close Malivore. It would explain the abandonment and it would explain why Landon doesn't know anything substantial about his past. There's also a fair chance that Landon may be a demigod or a Hunter or come from a line of a Hunter who was crucial to the closing of Malivore in the first place. 

While we don't really know for sure but when the show returns for episode 8, 'Maybe I Should Start From The End', it should potentially give us some more answers about Landon.

The promo teases him in a dangerous situation and Hope running off to save him. He had earlier been kicked out of Salvatore School for the Young and the Gifted and Hope had sent him to New Orleans to a friend, although it was never revealed who this secret ally was. Maybe we will know that too. 

'Legacies' episode 8 'Maybe I Should Start From The End' airs on January 24 at  9/8c on CW.
