Yeah.
They had a faerie ninja, an outsider-spawn caster (pretty much the leader), an outsider-spawn social butterfly/Hulk, and a fertility goddess with a ton of refresh in Incite Emotion and custom upgrades. They had recently acquired enough information about Harry's outsider-bane prophecy thing to know they needed him on the home team, and they wanted Bob to deal with some tangentially related stuff.
So they took about five minutes of discussion to decide on a gank, which is, by the way, only 1/6th of the time they spent discussing how not to hurt/whether to mindbreak Molly (they ultimately didn't, trusting Harry to keep her under control). Planning it took most of the session, executing it took about another five minutes.
It was basically foolproof: a cascade of previous events had opened the way for the outsider crew to gain recognition and clout in Faerie, which they spent a good hour trading on (along with the ninja, whose parent drove a hard bargain requiring a sacrifice of Refresh in exchange for a MacGuffin Maeve really wanted) for the end result of a major favor owed them by the Leanansidhe. That favor was, of course, passage into Harry's apartment. The outsider-crew entered, subdued Mouse fairly handily, and the caster began a ritual to take over Harry's wards from the inside. They had just bought the apartment above Harry's, from which the ninja set up shop.
Meanwhile, Harry is at a social gala with the intention of stopping some majorly bad Denarians (mine, not quite Nicodemus/Tessa level) from getting a huge foothold in Chicago. There aren't actually any coin-bearers, but there is our lovely goddess of cuddles, who launches a hardcore Social assault that quickly breaks into Mental territory. Harry bugs out and the numerous allies he'd called to the party for the nonexistent Denarians start in on the goddess, but she's a smart cookie and resists their efforts to clear out the mortal collateral, creating an effective stalemate. Harry has taken two Consequences and his 3rd and 4th Mental Stress boxes are checked, so he's no shape for a fight, and heads for his safe haven.
Upon arriving, he enters a short contest against his own wards before he's dropped in one round by the ninja. The outsider crew rescue the goddess in grand fashion, sewing terror and chaos and the groundwork for a proper cult, and hightail it back to Harry before anyone can get things coordinated (at this point, I was barely coordinated myself).
Short, brutal Social conflict. With nowhere to go and badly injured, Harry accepts an Extreme Consequence - Servant of Shub-Niggurath (or close enough), handing over Bob and pledging himself to the party's campaign service.
No one but themselves and Winter know that Harry's just switched teams, likely for good, and they're probably going to declare war on Faerie sooner or later anyway. Harry's friends and allies (including the Blackstaff) will likely investigate, but Molly is already being indoctrinated and the troupe won't be sticking around Chicago now that they have what they came for.
They're not actually an evil group, they just took character creation in a really weird direction. Like Exalted Infernals, I guess, they've got this really transhuman thing going on. Anyway, I figured this is pretty close to how most of Harry's casefiles start anyway, so I'll give them a break while I think on how to keep things interesting and draw them back into Chicago.
