BUDDY IS HER RUNNING MATE I HAVE TO KILL MYSELF
It’s possible this is a flashback. That looks like the same white dress Selina was wearing in the debate scenes.
But remember I said Amy might leave Selina again before the end of the show? This would be a good reason why. Yet again Selina would be forcing her to work with her odious ex, and I cannot imagine Amy working with Buddy for any length of time and not burning everything down.
