Jazz extended one of his datapads to show Prowl. "Now, I think this should – HOLY SLAG!"

Prowl knocked his chair over as he spun around. His optics got incredibly wide as his sparkmate glided through the wall with a smile. "Hello, mechs."

"Hi…" Jazz twitched. "How did you…do…that?"

"Simple!" Tai waved and phased her arm through a chair. "Oopsie. Don't quite have the hang of this thing yet! 'Jack made some kinda doohickey that attaches right here." She gestured to the small blue device on her collarbone.

"Phase displacement modulator," Riella pointed out. "Anyway, this is going to be quite a lot of fun, huh?"

CRASH.

Tai rolled her optics as Riella sighed. "Jazz, would you take Prowl to the medbay, please?"

The moment the two mechs were out of the room, the femmes grinned at each other. "Next up, Ratchet?"

"Do you want death? Ironhide's in the medbay."

"Then it's your dad. Next stop, Prime's office."

Optimus was in the middle of reading over a human budget report when his daughter fell through the ceiling and landed on his desk with a heavy thud and a yelp.

"Tatyana, have you been playing with the portal guns again?"

Tai giggled and shook her head. "No, it's a suit!" She lowered her voice dramatically. "I'm Shadowcat!"

"No, I'm Shadowcat." Riella dropped through the ceiling and landed on top of Optimus's bookshelf, crouching like a cat. "You're Movie Kitty, remember?"

"Same diff," Tai shrugged. "Hey Dad, watch this!" Before he could stop her, Tai had simply phased right through his hands and landed on the floor with a huge grin. "Awesome, huh?"

Optimus blinked. "How exactly did Wheeljack – "

"Don't know," Riella called from the top of the shelf. "We didn't watch. I suspect a manipulation of the portal technology."

"Thank you, Sheldon Cooper," Tai yelled back. "What's wrong with saying 'he used portals'?"

The Autobot leader shook his head with a smile and a sigh. "I suggest you don't go near Ratchet like that. He told Wheeljack to run all inventions past him before testing them."

"Good idea. Later, Dad!" Tai sprinted toward the left wall. Riella's optics widened.

"I wouldn't – "

"OH MY GOD!" Tai shot back through the wall. "Oh god!"

"Right." Riella slid off the shelf and sank a few inches into the floor before hopping back up. "I don't know why Leo feels the need to adjust his underwear in every other storage closet. So, next up, the big one?"

He was minding his own business, doing exactly as he had been told, when they entered his office. Without using the door.

"Hi, Red," Riella commented. "What's up?"

The head of Intel frowned. His door was closed. He would have heard it open. But here they were, Riella and Prime's daughter. "How did you get in here?"

"Oh, y'know," Tai answered casually, waving one hand in the air. "Just walked through the wall."

Red Alert's optics flared almost white as he stood up, almost knocking over his desk. "WHAT? Is there a breach in my security defenses? How is this possible? Prime must be notified!"

Riella frowned. "Red, you're speaking Cybertronian. And the answer is no, Wheeljack, and he already knows."

"That's not possible!" Red Alert scanned both of them rapidly. True, their suits were giving off a distinct image of new technology, but it was simply impossible. "How did he do this? How?"

Thud.

Riella snickered. "I'll take him to the medbay. I know we shouldn't do that, but it doesn't hurt him and it's fun."

"So true, sister, so true." Tai leaned on the chair leg and almost phased through it. "So, can we call this a successful test?"

"I would say…" Riella paused for a long moment, enjoying her friend's expression of suspense. "I would say that we need to get 'Jack to make these available for stealth missions."

Genius bonus for those of you who like trivia: Tai was originally compared to Juno (Ellen Page) in her debut story. So guess who played Kitty Pryde in the movies?
