Ripper follows with some long flat pillows he judges suitable for pinning the blanket down atop the walls.
"I haven't made a blanket fort since -" says Soph, and then she stops and shrugs and flops on Tony.
"Cozy as hell," he reports. "I've definitely never made a pillow fort this awesome."
"But snuggly!" he says, snuggling up between the other two.
"Now, I don't know about you two, but I know what I do with pillow forts when I'm done with them," says Ripper.
"Wreck 'em, of course," he says promptly. "Either with everybody inside, or in a huge pillow fight, or both."
Soph hmmmmms. Then she seizes a long foundational pillow and thwacks both of the boys at the same time.
Soph is nearly as unfairly good at pillow fights as Tony is at driving-oriented video games. They might have to gang up on her.
The walls of the fort are definitely beginning to sag after all three participants have pulled out their first weapons, but it's one of Tony's wild swings that thwacks against the ceiling and pulls one corner completely out of its supporting pillow structure. That end of the blanket settles gently down onto the combatants.
He manages to escape to the fort's opposite corner, where the blanket is still anchored.
Either because of something someone did or just because of the general ruckus, the side walls of the fort collapse soon afterward, dropping the whole ceiling on all three of them. Ripper starts giggling uncontrollably.
Soph pops up like a daisy and picks up the pillows that were holding the ceiling in place as long-range weapons.
Tony wriggles out from under the collapsed ceiling to discover that the archway is the only part of the structure still standing. He whoops. "Engineering in action!"
