Ok, so Landon and Hope are immortal and also both have been born even if their parents couldn't have kids(Klaus and Malivore).
Also Both of them can be killed only by one weapon(the golden arrow and the red oak stake) and both have immense power(phoenix and tribrid powers)
So what if both of them are gods?
The thing that really makes this theory possible is the fact that Hope put Alaric in coma and Alaric arrived in Limbo.
The Limbo is for humans and supranatural who died not humans who ended in coma. Alaric was still alive, even if it was nearly braindead.
So what if Hope used a power that she didn't knew she had.
I mean it could be a nice twist if they reveal that Hope is the God of Death and Landon the God of Life or something along those lines. Also these will tie in with hope new status of Undead and the fact that Landon is the only immortal without undead status. + It will go with the new god storyline and maybe give some new powers to Landon while giving his old powers back.
