The sight of three characters demanding that a fourth remove her panties for them, in public ... requires a certain amount of meticulous set-up not to look sordid, doesn't it?
But talking of set-up - this is pretty obviously a risky feint to buy Adora the time and opportunity she needs to make her move. She's got the crucial knowledge and resources here, but she's currently remaining off-stage. She wants the edge of surprise.
However, I have a bad feeling here for Brooke's chances of making it through this scene without serious injury. She's been doing a bit too well recently. She's developed the smarts to put one over on Cerise, the confidence to take the lead in facing down Chloe, the maturity that made her take responsibility for Kade as well as this, and comfort with her own complex sexuality. Plus, she seems to have command of a monster form that has to be pretty tough if her challenge to Chloe isn't a wild bluff. In general, characters who get that far ahead of the game in this sort of story can only avoid turning into Mary-Sues if they take a severe, lots-of-angst-for-everyone-else-round-the-hospital-bed sort of beating.
