"Dad's gonna kill me," Blaine Anthony Anderson Stark moaned, taking in the ruins of the mansion.

"Well at least we know that our experiment worked," Sebastian Bruce Smythe Banner offered, also taking in the smoldering ruins which used to be the Stark mansion.

"It did, didn't it?" Blaine's face broke into a grin.

"HOLY FUCKING SHIT! WHAT THE HELL HAPPENED?!"

The smile on Blaine's face instantly died as the Avenger jet had silently touched down and they had disembarked. Apparently, Tony had noticed that the house was no longer anything but a smoking, smoldering mess. A portion of the East wing decided at that moment to collapse on itself, causing both Blaine and Sebastian to cringe. The boys turned to face the approaching adults.

"Um, hi, Dad," Blaine said rather sheepishly.

"Sebastian," Bruce looked at his own son sternly. "What did you do?"

Sebastian got a petulant look on his face. "Nothing," he said flatly.

"Blaine? What happened? Are we under attack?" Tony was still trying to wrap his head around the fact that the mansion was gone and what could have caused it.

"Um, no, just a minor accident in the lab," Blaine hastily explained, glancing out of the corner of his eye at Sebastian.

"You call that a minor accident, Bud?" Steve asked, his gaze taking in the fact that another upper floor was collapsing into the lower floor in the main portion of the house.

"Yes, because nobody died. So minor accident."

"What the hell were you two doing?" Clint asked, coming over as well.

"Can't answer that," Sebastian replied. "State secrets."

"Kid, you're twelve. You don't hold state secrets." Clint narrowed his eyes at the two in suspicion.

"You'll need plausible deniability when the fire department gets here," Sebastian explained, rolling his eyes. "And I may be twelve, but I'm not stupid. The insurance adjusters are gonna find some - things - that will really question whether this was an accident."

"Blaine?" Tony turned worried eyes on his own twelve-year-old.

"Sorry, Dad, but Seb's right. State secret." His eyes widened slightly as he realized something. "Oh shit! Seb, the array!"

Sebastian's own eyes widened and they both took off running towards the open field to the west of the estate. "JARVIS," Blaine yelled into his i-phone. "Dis-activate the self-destruct on the array!"

There was a sonic boom which blew them off their feet and a minor explosion as the array blew itself to pieces. Both boys sat up. "Dammit," Sebastian cursed, as they both stared at the mushroom shaped cloud floating up from where the array had originally stood.

"Dad's gonna kill us," Blaine moaned again. They stood and brushed themselves off as the adults surround them again demanding answers.

Sebastian just sighed. "At least the experiment worked," he offered again.
