Bruce and Tony followed Catrin downstairs. She stopped at the door to her room.

"Everything else looks okay, but...things aren't where I left them in here. Almost, but not quite."

"Is anything missing?"

"I don't see anything so far. My computer and my jewelry box weren't touched, or my backpack..." she scowled. "Only thing I can't find is my hairbrush, but I probably threw it in the laundry again." She moved to her hamper, stuffed with wrinkled jeans and t-shirts.

Tony stiffened. "Check for it," he said in a tight voice. DNA source...shit, shit, shit...
Judging by Bruce's expression, he'd had the same thought.
A more thorough search still didn't turn up the brush. Bruce examined the doors to the house. The front doorknob held faint scratches, as if someone had used a lockpick. Clumsily, but they'd gotten inside.
Not a thief, or valuables would be missing... He checked for any hidden devices, either bugs or, worse yet, explosives or poison, but came up empty on that front.

"We need to get them away from here. All three, " Bruce finally said.

Jim had woken up, by that point. He concurred when Bruce said that. He and Alexandra would go to stay with friends out of town for a few days. Bruce planted a few devices of his own in the house, to alert him if anyone entered once they'd all gone.
Catrin, it was decided, would return to Gotham with Tony and Bruce. They'd stay at Wayne Manor until Bruce's heat was over, then Tony would fly back to NYC alone...temporarily.

Despite the worry they all felt, Catrin couldn't help also being elated at a helicopter flight...Tony had promised to give her a lesson in the basics of piloting. She packed up some clothes and her laptop, her birthday gifts, and headed out with her fathers. She gave Jim and Alexandra a tight hug, but none of them said goodbye. Just 'see you soon."

The AIM scientists were very interested in the DNA they extracted from the hair sample Rumlow brought them. They confirmed for him that the owner was Stark's daughter, from an Omega parent--probably male. And that she was old enough to have presented as Alpha, but not fully adult yet.
That would make some things simpler; if they wanted to brainwash or mindwipe her, a younger victim had fewer defenses against that sort of thing. She might be useful if she had inherited Stark's genius-level intelligence.
Even without, she'd be a possible chink in Iron Man's armor, or a valuable bargaining chip.
He was given authorization to add her to his list of targets, though his superiors specified that she was no longer considered expendable.

Rumlow smiled. This was going to be much more profitable, and interesting, than he'd first thought...and he'd already had high expectations.

Alfred welcomed them back to Wayne Manor, genuinely pleased to see all three of them. He'd met Catrin once before, but that had been almost a decade ago. He was touched when she recognized him. Bruce chuckled when she asked shyly, "Alfie? Or--no, not now. Sorry, Mr. Pennyworth--"

"Quite all right," the butler said kindly. "Alfred's fine. Don't fret, my dear. I'm glad you've come. "

He led them to a sitting room, had them take chairs while he made tea and caught the men up on recent events.

"Any problems while we were gone?" Bruce rubbed at his face, sweating a little. He found it difficult to pay attention; he kept wanting to be left alone. Or, not entirely alone, he amended, glancing at his husband. Tony smirked a little, but twined his fingers through his husband's. Soon, he mouthed.

"Er. Actually...not in Gotham. However, there was some...excitement...at Stark Tower this weekend... Mr. Hogan has placed Steve Rogers and Natasha Romanoff under 'house arrest', as it were. Though the house in question was intended for Dr. Bruce Banner, as I understand it."

Tony's face hardened. "What did they do?"

"I believe Master Grayson would like to be the one to tell you that particular story...when you're both able to hear it." Alfred motioned to a table across the room. "He said to ask you if he could keep that. I did advise him not to get his hopes up."

The vibranium shield gleamed faintly. Tony blinked. "...Huh. Cap's being more of a pain than usual, I'm guessing?"

Bruce snarled at the mention of that name from his mate.

"Easy, love," Tony focused on him. "Ah. Alfred, look after Cay, please? We'll be upstairs. No disturbances unless the world is ending--and don't take Rogers' word for that," he added belatedly, grinning. They beat a hasty retreat to the second floor.

Catrin giggled, looking at Alfred. "You ready to handle another Stark-Wayne in a few months?" she asked saucily.

"I don't believe anyone's ever ready for that." He lifted his cup, hiding a sudden nervousness in a mouthful of tea.
