Concept: Vlad starts reconciling with the Fentons, like for real, simmers the hell down and talks to them like a person. Starts being around more often, even gets to the point where he and Danny aren't at each other's throats constantly. Eventually gets comfortable enough to consider telling Jack and Maddie about his ghost half.
And then Jack dies.
It's a freak accident, but it puts Maddie WAY more on the anti-ghost defensive, so he sure as shit can't be doing any dramatic ghost half confessions now. Despite bad interactions in the past, Maddie ends up leaning on Vlad for comfort and somewhat expecting him to take up something like a parental role with Danny and Jazz—there's no romance, just the fact that he's there and should be helping now that Jack is gone.
Meanwhile, Danny immediately suspects Vlad had something to do with the accident and will hear no defenses. He makes it his life's mission to prove it was Vlad's fault because he just can't believe it was random circumstance. Jazz isn't sure what to believe but is too focused on keeping her mom and brother somewhat sane to be of any help to Vlad.
So ostensibly, Vlad gets everything he wanted—Jack gone, Maddie to himself, power over Danny—but also he gets literally nothing he wanted—he didn't get to kill Jack, Maddie doesn't love him, and Danny is further away from trusting him or accepting him as a mentor than ever before.
