I find it hilarious that your more sensible theories, like Alfor was the Yellow Paladin, were totally wrong, while your more out-there theories like Zarkon being a Quintesence-powered zombie were perfectly on point. You should make weird predictions more often!
I’m still not over Red Paladin Alfor being canon honestly. I can buy it gradually as I’m going back and thinking it over but I guess the stumbling point is- Alfor’s final decision was such a Yellow Paladin thing to do, I guess it didn’t occur me that everything was coming to pieces for him and it probably meant his personality was deeply diverted from his usual, true self. Seeing flashback Alfor helped me believe it, though. Makes me wonder if Allura just overheard one of the team griping about Keith flying them off a cliff and Keith being like “It worked didn’t it” and Allura’s just, “ah, yes, that’s the red one.”
But yeah, though, Zarkon space dracula confirmed, Voltron as a benevolent space horror confirmed. Zarkon and Haggar are married and just really quiet about it, confirmed.
Lions telepathically nudging Allura towards their favorites sunk apparently, which, raises a lot of questions and makes me wonder if Allura is a low-level mind reader. We’ve seen several interactions where the team is tricked but never one where Allura herself is actively deceived- even the s3e4 alter-dimensional evil-alteans clearly believe everything they’re saying. Allura may be able to read people emotionally.
