Because if there's anything Danny hasn't had enough of, it's weird old men who want to test his potential, amirite??? (I have not actually seen Danny Phantom outside of the episode where Sam turns into a dragon, but I understand this is basically Vlad's role.)

iirc you mentioned in the discord that Danny is going to have at least one "overextends himself trying to close a voidtear on his own, like a heroic dumbass" scene, so it occurs to me that we could have Rezo notice that Danny is starting to struggle and barge in to take over before he passes out, because I imagine it would be really awkward for Danny if this happened. nbd if you don't feel like it though!
