• Mary is attacking Spencer or someone who looks like Spencer (maybe a mask or Spencerietta)
• Wren is shooting a gun
• Mary is out of jail (????)
• After ALL the struggle Aria decides she can't marry Ezra, I wish this scene has something to do with EzrA, but knowing Aria is probably some random drama.
  
• Addison is back, I hope this has nothing to do with what Marlene calls "full circle"
  
• Is that Melissa in the horse scene? This scene gave me some major flashback vibes, also Jessica D used to take Bettany to this horse place, remember? or am I confused? Maybe Bettany and Melissa are somehow linked to this horse thing.
  
• Mona is back at Welby and gets A visit.
• There's an outdoor dinner thing, I don't understand it, it seems like the Hashtings backyard, but I'm not sure. Also I recognize Ali and Emily, Hanna and Toby and someone who I'm pretty sure is Spencer because of the bangs.
• I see two people running, they seem to be Ezra and maybe Emily and the place looks like a train or a tunnel, or maybe a hospital because of the lighting, but idk.
• Spencer and Toby are having sex, maybe Spoby will have a happy ending after all.
• When the narrator says: "AD is revealed" we see a snow globe falling, we know that snow globes stands for Jenna, also we see Jenna in 3 scenes. I don't think she's AD, but she's involved somehow.
• Mona is wearing a black hoodie and hitting Spencer, 2 scenes of Spencer being hurt, first by Mary and now by Mona.
• We see Spencer hugging someone, I would say it's Mary Drake because of the black outfit, but who knows?

So guys, I'm sorry everything is out of order, but I've watched the promo several times to catch everything. I hope the finale gives us some closure.
