Alaric and Damon (spoilers)
I really hate that their friendship has come to this. I understand that Damon has been committing irredeemable acts, but at the same time, I have to think that the deal he and Stefan made with Kade was done at least partially to save the girls. I think he's definitely still in there somewhere and his humanity is fighting.
But to see Ric actually "kill" him is heartbreaking. I loved their friendship for the first few seasons. But since Ric came back, he doesn't fight for Damon at all anymore.
I like Damon and Bonnie's friendship too, but Damon/Alaric always had this deeper connection to it. I loved how Damon mourned after Ric died. I loved how Ric watched over him from the veil. Ric was Damon's only friend for so long. It sucks to see it in such shambles.
I was happy when they brought Alaric back. But I feel like it has been a mistake ever since.
Sorry for rambling. This season just seems totally bizarre in the realm of the character depth and development we saw for so long. It's like they just threw character continuity out the window in so many ways.
