Small part I thought of..
Packing for the trip, Carly gets a call from Packie, asking if she's seen Dash.
"She might be in trouble, I'm leaving t- (the phone is dropped from Packie's end, and he's heard running out of his house) Hello? Packie you there?"
Somehow Packie made it to Carly's house within seconds, and burst open her door, shouting.
"WHO DONE IT!? DID SOMEONE HURT ME SISTER!?.. I will makes them pay!" Packie said, showing to have a blow torsh before saying the last part. And after saying it, did a test blow.
"Whoa, whoa, calm down Packie, she's trapped in Philly during that green flu.. Save it for the rabit zombies" Carly said.
"Fuck yeah! Lets kill us some zombies!"
