Arrow
Okay, you know what would have been funnier than Sara bringing Ollie to that dinner? Sara bringing The Arrow. C'mon, it would've been great! Ollie all done up in the hood and mask, growling "pass the milk, please" in a vaguely threatening way. "We're bringing co-workers to family dinner now?" "He's my Vigilante Club partner, Dad! We have a buddy system, I couldn't just wander off without him!"
IT STILL WOULD HAVE BEEN A BETTER IDEA THAN BRINGING UNMASKED OLIVER. Sara, sweetheart, I like you a lot - you punch bad guys with panache, you have a big heart, you're kind of easily led by supervillains, hey, we all have our weaknesses - but in what possible way was that going to make things easier between you and Laurel? Good GOD.
(…you know, Team Arrow totally should have a buddy system.)
