Well i'll start with SPN. For that show i wanna see how they handle Lucifer/Nick along with Archangel Michael. It appears he still has a hold on Dean just dormant. I wanna see dark Kia and them make a deal for the spear. Maybe a temporary team up.
As for Legacies I wanna see more about the Necromancer. Who is he working for? Why he and everyone else want the knife? I also hope they give us a potential fight between MG and Kaleb. It seems like it can happen. Also some archive footage from TVD and TO would be cool in relation to Hope's psyche(this isn't a big deal but would be kinda nice but not necessary.)
is lucifer still walking and talking? I had skipped a few episodes this season so im not caught up yet but i did see last episode, yeah im hoping they go all out team warfare and gain every ally and every weapon, they need to treat this as a season finale
yeah i have some hopes for legacies too tonight but its not much. They've exhausted almost everything in a span of 9 years/14 seasons
