Sources: TVD & TO
[Spoiler (click to open)]
I think they're finally trying to course-correct with TO. It looks like they're finally ending Haylijah & Klamille for good. It's taken them way too long to bring back Kol & Finn. It's what should have happened in Season 1, but I think it's too late the save the show.
The Steroline break-up was obvious from the start of the season, but it should have been written better. TVD is clearly jumping 3 years ahead when they return, so no more flash-forwards we'll just be in that time-line.
