Kalista being a Darkin?

https://www.youtube.com/watch?v=DFZJuBXufIM https://www.youtube.com/watch?v=vsHsGLYR4WM Am I the only one who sees the similarity? Anyone else? Or is it just me? Had me thinking Kalista could be a Darkin. Specially considering the fact that Aatrox is the Darkin Blade. And Kalista is the Spear of Vengeance. A theory: Each Darkin has a representing weapon and is the spirit of something. If that were the case, Aatrox would be the spirit of war who wields the blade. And Kalista would be the spirit of vengeance who wields the spear. Now a second theory which would make more sense then the first, but is related to the first. What if the Darkins were actually the weapons and not the champions. It would actually make more sense that way considering it says "The Darkin Blade" and "The Spear of Vengeance" it's not referring to the champion, it's referring to the weapon. And each weapon fills it's wielder with it's theme. (i.e. War and Vengeance) Or maybe the weapons choose the one best fitted for it's theme as it's master. Or maybe both (The weapons choose the best fitted being to wield it, then pours even more of it's theme into the being.) Maybe that's why Aatrox can't stop talking about war and Kalista can't stop talking about vengeance. xD No seriously... it makes sense...
