There was a loud noise coming from the lab and seconds later Henry's voice filled her ears.

"Ahm... Doc... We have a problem over here."

Helen sighed, wondering what had happened this time. Nikola and Henry had spent the last couple of days in the lab on some new invention. She hadn't exactly bothered to ask for more information than was strictly necessary. She walked over to the lab and stopped as soon as she entered.

"What happened here? Where's Nikola?"

Henry bit his lip and raised his eyebrows; he was so not looking forward to tell her the news. He pointed to the far corner of the room and stepped back to let her pass.

"Henry..."

"I don't know what went wrong, Doc. I'm checking everything but there is nothing. I'll work on it."

Helen sighed heavily and kneeled down, smiling at the two dark orbs looking at her.

Will entered the lab that second and frowned when Helen walked back to them.

"What happened here and where's that kitten coming from?" He asked once he had spotted the kitten in Helen's arms.

"I'm afraid that's Nikola..." Helen smiled.

"What the hell happened here?"

"Dunno yet."

"Henry, you figure out how to redo this and I'll take care of him until then... Will, maybe you can help him a little. The faster the better."

The boys looked at each other and shrugged while Helen left for her office, sighing again with a kitten-Nikola snuggling into her arms. She had to admit though, he was really cute with his dark eyes and the black fur. She absently let her fingers go through his fur and heard him purr softly. She couldn't help the small chuckle and shook her head when he lifted his up to look at her.

"Don't look at me like that."

They reached her office and Helen sat down on the couch shortly, placing Nikola next to her. Her head fell back on the couch and she closed her eyes. This was going to be a hell of a day.

Nikola decided to climb up the sofa to lick her face in the meantime. She smiled and opened her eyes again when she felt it, scratching him.

"I have work to do, though. You stay here. Take a nap or something."

She got up and he meowed in protest. He wanted attention. He wanted her attention. She ignored it and sat down on her desk, glancing up at the kitten then and there.

Helen worked on paperwork still when Nikola was bored and jumped on her desk, walking over the keyboard and her files.

"Niko! Not now; I have work to do."

She didn't hear how Kate entered the room after knocking gently.

"Wow, when Will said Tesla was turned into a kitten I really didn't believe him." She said when she spotted him on the desk.

Helen looked up at her helplessly.

"You ever had cats? I don't know what to do with him."

"Well, since this is still Tesla, I'd say he wants cuddles, scratchy and some attention from you. So, same as ever, really."

Helen glared at her but the smile on her face gave her away.

"Did you need something?"

Kate came in and stepped to the desk, scratching Nikola shortly as he looked at her and she at him.

"No, actually. Just wanted to see for myself." She said, "He's really cute like that. Are you sure you want the old one back?"

Nikola turned his head and she could swear he was offended. Kate laughed and waved her goodbye before leaving again.

Nikola looked back at Helen and tried climbing on her shoulders but she grabbed him before he could and placed him in her lap, scratching softly.

She felt like some epic super villain from a clichéd movie.

"Seriously, what am I going to do with you?"

He seemed to ignore her question as he snuggled into her. Laying his head on his paws he made himself comfortable. She kept stroking through his fur until he fell asleep. Helen sighed but smiled. She tried working some more and after her current file was done, she leaned back and watched Nikola for a while. She didn't want to wake him up already. Helen had absolutely no idea how to handle a little kitten; yet alone Nikola as a kitten. She somehow fell asleep a bit later until Nikola woke up again and meowed until she awoke.

Helen stretched to get the uncomfortable feeling out of her body and looked down at him.

"Hey, are you hungry?"

He meowed again and she took that as a yes. A glance at the clock made her yawn: It was two in the morning. She had slept around three hours or so. Nikola jumped on the desk again and then down on the floor before walking to the doorway where he waited for Helen to follow.

They walked to the kitchen together and she looked for something to give him to eat. She smiled when she got lucky in one of the shelves.

"Looks like the BigGuy likes your new self enough to get you some actual cat food." She mused and grabbed a plate to put the food on it.

Nikola couldn't wait to eat; he was starving. He didn't even care that it was cat food as long as he got food. When she finally placed the plate on the ground there was no stopping him. After a while, he sat upright and used his paw as a fork. He shovelled the food on it and then licked it off.

Helen shook her head, laughing softly at him. Even as a kitten... Really?

He looked up at her, possibly confused and her laughter ebbed down to a soft chuckle. Nikola turned back around and continued eating for another minute.

"Now, we should go to bed... I can't believe I just said that."

Helen could swear she saw a smirk on Nikola's face and she rolled her eyes.

They reached her bedroom and he almost instantly jumped on the bed and lay down on one of the pillows. Helen tried to look offended but he looked so cute laying there and looking at her like that that she really couldn't. As if he knew what she was thinking, he rolled onto his back and raised his paws, his eyes fixed on her. She nearly aw'ed out loud, almost forgetting that the adorable little kitten on her bed was Nikola Tesla. She smiled and crawled under the blanket before scratching his belly. He was meowing and purring, signalling her that he was happy and her smile softened further. She let her finger trail over the bridge of his nose and he rolled back on his paws, walking the few inches over to her. He licked her cheek and nose before she cuddled her face in his fur for a few seconds. She gave him a soft kiss on his head before she made herself comfortable to sleep. A smile spread across her face when she felt him snuggle in right beside her.
