[X] Where's a phone booth when you need it? – You don't want to leave anyone to get hurt by these Rats, but you owe it to your dad to keep your secret. Use the inevitable chaos to find a corner in which to change.
[X] Step 1: have Perfect Storm call the PRT and let them know that Rat Case 53's are crashing a party at... where ever you are. While Perfect storm makes that call use your telepathy to contact Samantha and have her inform Danny. All this while diving under a table to hide? Why yes. Now get your Barrier Jacket on and get moving!
-[X] Step 2: Cast Recursion Field, Exit the house, and get into the sky - it should trap the rats right? They are capes of some kind. But even if it does you don't want to stay on the ground with them.
--[X] If you catch the rats in the field, warn them: "Surrender or die!" You've always wanted to say that to someone after all, and now seems as good a time as any.
---[X] If the Rats surrender have Perfect Storm call the PRT again if he can to get an ETA on backup and prisoner pick up.
---[X] If the Rats don't surrender... Cast Solar Wrath: Lethal. If they want to try and kill innocent children then they deserve what's coming too them.
---[X] If the Rats don't surrender... but you catch someone else in field too, a cape you didn't know was at the party, teleport to them and then back into the sky. Sure, it'll be tiring, but you only really need to delay until the PRT arrive. Doesn't mean you won't blast away with some lethal Flare Shooters though.
--[X] If the rats aren't caught in your Recursion Field then cast Temporal Sludge, Strong Shield and Flare Shooter set to Lethal. The rats shrugged of your stun shots last time and if it comes to their lives or the lives of your school mates... So do your best to try to delay the rats while the party goers flee.
---[X] Save any stragglers with spatial translocation if you have too. Whether that means putting yourself close enough to erect a barrier, teleporting the victim away, or tanking the attack yourself, you'll do what you must to save them.
Edit: Changed my vote to Major Session's plan cuz it does cover quite a few bases and seems well thought out. I'm all for it.
