Maybe I'm in the minority, but I really don't see the huge issue with Mona and Mason. The age difference is a little strange, but dating between students and faculty at a university is not the same as it is in high school. She's not his professor and doesn't really have a direct position of power over him, so I really don't think it's a big deal. That said, they really shouldn't be drawing direct comparisons to Aria and Ezra. Noooo.
I enjoyed Ali and Gabriel, and I appreciated the normalization of open marriages (it's not for me, but it's a valid and normal choice). I'm so glad they actually kissed, to spite the nasty Emison shippers if nothing else (speaking of which, I don't recommend going on Twitter right now). I've seen so many people calling that storyline unnecessary, but they're missing the point. It wasn't about Ali and Gabriel. It was about showing that Alison is over Emily and has moved on. I wonder who her first actual, major love interest is going to be.
Speaking of which, did anyone else pick up on the vibe that Taylor's developing some feelings for Ali? Her attitude toward Gabriel was stand-offish at best, and the way she gazed after them when they went off to get drinks...everyone seemed so set on a pairing of Taylor and Mona, but it seems like the show might be moving in the direction of Taylor/Ali instead, which I hate. They've been compared to each other so much that it would be super creepy to me. I really want Taylor to turn out to be evil and trying to steal Ali's life or something.
I literally yelled out "Dylan, no!" when it seemed like he was agreeing to Booker's offer. As interesting as that could have been, it would have destroyed any semblance of the friendship that's blossomed between the three Perfectionists, and that's a part of the show that I've really started to enjoy.
So now Mona's story is that she found out about Beacon Guard spying on students in the bathroom because she's just that good, and has been keeping it a secret? That's bullshit. I can't wait to find out what her true involvement is, because she's obviously not being truthful. Along similar lines, there was an interesting moment during her and Booker's speed dating round, with Booker asking "Where is your safe place?" and Mona responding "If I told you, it wouldn't be safe anymore." That took me right back to the pilot, and the woman behind the mirror telling her to "go to your safe place."
