People I follow on Tumblr are into many fandoms that I don't know, so I do sometimes see what is going on out of curiosity. For a while, it was The Flash, because I wanted to see how they were going to treat Iris/Westallen (I thought they looked cute in the trailer but didn't trust the CW after Arrow and Supergirl). Last year, after that whole love confession went around, I have to admit I was halfheartedly curious about where Supernatural was going to go in their final episodes, but I hadn't paid attention to it before that and only knew the bare details.
Sometimes, I check in on Riverdale. I don't have any interest in watching the show but as someone who used to read the Archie comics growing up and have a couple people I know online that do watch, I am interested in what direction they're going to finally go in.
Yes, I am the type of person who is always tempted to skip to the end to see what happens in everything. :D
