Finally saw it (stupid internet).
Holy crap, I think that was the creepiest episode ever! Even after reading this thread, I still was legit totally freaked out when we saw Garrett. Like, I didn't even anticipate that he would be in the box with Aria... ugh, sends shivers up my spine even now, can you imagine??
And I LOVE LOVE LOVE the idea that Byron killed Ali. I don't know why, I just do. I hope that's it. I already don't like him and it just fits so well with his general creepiness and asshatery.
All the girls looks gorgeous. I loved how ridiculous Emily and Paige were on purpose, Hanna looked adorable, it some how fit that Aria would pretentiously dress up as one of my least-favorite literary characters of all time (I hate, hate, hate Daisy Buchanan. Hate.), and wow, Spencer was a bombshell. I remember that when I first started watching this I actually thought Troian was less pretty than the rest of them. I now have no idea how I ever thought that.
Also, they should stop having her interact with other character's significant others, because it doesn't matter who it is, Troian has better chemistry with them. I swear I could realistically ship Spencer/anyone on the show. For the like 3 seconds Paige and Spencer were alone onscreen I was like, woah, and she still has super awkward amounts of chemistry with her half-brother. I seriously hope Troian has a fabulous career after this show is over.
