Penny's would probably be recent/canon history, but might include:
- sitting frozen in a classroom while a man with moths fluttering around his head rips the eyes out of the professor at the front of the class
- appearing in an asylum and seeing a racist version of yourself mopping the floor while the douche you know is whining about being crazy
- having crazy telekinetic/floating sex
- migrating as a goose to Antarctica
- idk lots of other random magic shit


Costigan:
- beating up a gym teacher with a folding chair as a teenager
- sitting across from Jack Nicholson who's waving a bloody, severed hand around while talking
- shooting a guy in the knee while being told he didn't say what you think he said
- mom's funeral
- helping to beat the shit out of a random guy
