Dude I can't wait for season 4. I love the show in general, but I think season 3 has been my favorite and I can't wait to see what happens next. I am still really upset about Allison, I hate that Isaac won't be on the show, and the twins! I'm gonna miss them. But with everything the show has to offer I'm sure it'll be great.
And I don't even know what to think about Katie. My friend and I were talking about how we thought she was coming back like 2 weeks before the finale or that was our theory and now she's back and all like a weird smurf thing with fangs like you said. And I don't even know. Like I couldn't stand her in the first season, I doubt I'm gonna like her now. But I guess we'll see.
