Star vs. the Forces of Evil. Nefcy sometimes uses emojis to write "Star vs. Evil" as (star) vs. (skull), so I think this is just the title + probably a general summary.>Arm/Rainbow/Glove
This may be referencing the scene from the promo where Star tests a bunch of spells on Marco to display his fighting prowess.>Diamond/Balloon
Moon gets fully soul-sucked. Remember they float like balloons.>Unicorn/Tree/Comet/Flame/Crocodile/Fight
Pony Head, Kelly, Hekapoo, Tom, and the dragoncycles fighting off Meteora. Some of the Marcnificent Seven basically.
Alternatively, meteor for Meteora and crocodile for Rasticore or even a last-minute twist connection to Toffee. Flame and Fight obviously reference whatever fight goes on when Star and Meteora cross paths, or Meteora with Marco's group.>Tragedy/Comedy
General emotion of the whole thing, also signifying DRAMA.>Painting/Broken Heart
Star's new tapestry as a queen of Mewni?! Yep, I think they're going there. Moon's dead or as good as dead.>Club/Heart/Spade
All that's left of the card suits by the end of the season.>Dress
Star wearing a queen outfit because by the end of these episodes she'll be the literal queen of Mewni, not just holding down the position until Moon returns.
I really don't think this is meant to be a point-by-point summary of both episodes, just really general stuff without touching on specifics.
