"Scissors!" you yell, making frantically for the door.
"What? W-wait, are you sure that's-"
You bolt from the room. Jack stops mid-protest to follow you. He catches up just as you grab the scissors triumphantly from their drawer.
"Are you sure that's a good idea?" he finally asks. "It would be a shame to ruin these, wouldn't it? The zippers are probably hidden as a safety feature or something. I'm sure there's a tab somewhere to release them."
He has a point- but then you see his wide red tongue hanging out between his canine canines and shudder. Are those flecks of saliva dripping from it? No, these costumes are freaking you out. Best be rid of them immediately. You say as much to Jack.
Jack shrugs his furred shoulders. "It's your costume," he says, though something about the way his tail droops makes his otherwise hidden disappointment obvious. "Just leave mine alone, okay? I'll figure it out the hard way."
