Flashback: Alison tries on all of these dresses, flirts with Emily, is a bitch to Spencer, overlooks Aria, and calls Hanna fat. If you've seen one single flashback, it's exactly like that.
Mom: "I want you guys to put on these dresses and march around for my sick pleasure in the public arena. Things have gone from bad to worse in the old noggin."
Hanna: "That is fucking fucked up. Look, pretend this chair is Alison and you can say whatever..."
Mom: "Therapy Anne, huh? Not even she can help me. Only Bloody Mary can save me now."
Hanna, once Mom bounces to see a man about a horse: "No. No way."
Liars: "It's not like she actually wore them. It's not like she was wearing them when she died. They're just dresses. We're going to be in a fashion show anyway."
Hanna: "These are all perfectly valid things in and of themselves, but it's still freaky and weird and fuck this."
Mom: "I'm back and sadder than ever. Oh, and the board has already signed off so there's no backing out."
God I love this show. What board is this, exactly? Just The Board. Just the specific group of people you call up drunkenly at noon whenever you're a Rosewood mover and shaker who needs to get approval for girls to wear outfits. That Board.
Spencer: "I'll tell the committee. About how we're wearing dresses now, in this fashion show."
Liars: Long conversation about how they are going to have pictures of Alison projecting on the wall while they wear her outfits, like a tribute, because what Rosewood needs to do is take just a moment out of the hustle and bustle of daily life to remember the death of Alison DiLaurentis that they are constantly discussing and thinking about and mentioning and obsessing over.
Liars: "Do we have to pass the pictures by her mom make sure she's okay with the ones we choose?"
(No reason to reproduce that line, it just sounded super weird and I thought maybe it was an intensely regional way to get that concept across. Like how on Secret Life and before that 7th Heaven the people always get put "on restriction," instead of grounded, and it makes you feel like you're watching secretly Canadian television.)
Aria, jumping at her chance: "I'll pass them by Jason! I volunteer!"
