A/N: This took longer than a day or two, my apologies. Work has taken up all my free time, but here's the next instalment! Thanks for all your comments, favourites, and reviews!

The team was called out on several cases back to back, so they never exactly got to talk. Regardless, Derek was doing his best to move forward and prove his commitment. "We have plans Saturday night!" he announced, walking into Garcia's lair one day.

"…We do…?" she hesitated. "What kind of plans?"

"JJ and Will are attending a gala for the PD, and we're going to their place to babysit!" He grinned, proud of his planning skills. This would be perfect, they could take a dry run and see what it was like. He could see if he really was as good with kids as he hoped he'd be. He already knew Penelope was a natural; he couldn't wait to have a houseful with her.

"Babysit…? JJ wouldn't leave Michael, he's a newborn and-"

"He's almost three months old, and their second kid. She's a pro, and besides. I offered, and she said yes."

"You di- she did?!"

"What? You don't think they'd trust Uncle Derek and Aunt Pen with their boys?" he smirked.

It wasn't that at all. She wasn't sure he wanted to. She didn't want to corner him, and send him running. She was surprised he hadn't yet, but… he did offer… "Saturday, you said?" She gave him a small smile. She was excited to spend time with her Godsons. And of course, with him.

It was Saturday at 8:34pm, and Penelope was now singing an entirely different tune. Henry had been running around all day, and Michael had been fussy. Michael now had a fever and was crying for the past hour, and Henry wanted to stay up with her and Derek. He wanted to watch a movie, but he cleverly insisted it was because the baby was crying. Frazzled, Penelope wiped the sweat off her brow, and resumed her negotiation with her oldest Godson. "C'mon, buddy, if your parents come home and find you awake, they'll be soooo upset!"

"But I want to watch Spider Man 2 with you! You promised!" he pouted.

"I did, but that was earlier. Remember we were going to put it on, and you wanted to watch your cartoons instead? You had a choice, and you chose your shows."

"Aunt Pen… Pleeeeease? I promise I won't tell mommy. Or daddy."

Just then, Derek walked in the room, rocking Michael. "Ok, little man, let's go. You said you were going to show me that book you were reading!" he announced excitedly, not leaving any room for argument.

"But Mikey's crying!"

"Here, I'll take him…" Penelope offered to Derek, trying to hide her pout. She tried gauging his reaction; he was probably exhausted and frustrated. This was not a good idea at all.

"Thanks mama, I'll take over as soon as I'm done. As for you," he smiled over to Henry. "You got me all excited about your book, you can't let me down, now!" and Henry raced off to his room.

"That was brilliant," Penelope smiled, sadly. He just winked at her, and followed the boy.

When he came back, he could hear sniffles in addition to the already crying infant. He followed the sounds to the kitchen, and found Garcia pacing and crying. "Baby girl?" he walked over.

"Oh, Derek!" she cried, hiccupping. "He threw up all over me, and… And he still feels warm, and oh…." She sniffled again. "This was a horrible idea. I'm terrible at this, and-"

"Breathe, sweetheart… I promise you he's fine. His fever was only at 100.1, it's common for babies. Besides, we gave him the medicine," he glanced at his watch "and it should be kicking in any time now. Calm down, if you're all worked up he's going to get even more upset. Here, let me try…" he offered, taking Michael in his arms. "You're alright, buddy… you'll start feeling better in no time…" he cooed, and sure enough Michael began to quiet down.

"How'd you do that?" Penelope asked, trying to wipe her shirt.

"It's probably my deep soothing voice…" Derek wiggled his eyebrows. "See? He's fine."

"How do you know? If JJ and Will get back and anything happens, I'm g-"

"Cool it, Baby Girl!" he chuckled. "My mom's a nurse; growing up, a few of my cousins were sick a lot and momma would always explain things to my aunts… I have a good memory!" he grinned, trying to make her feel better. He walked over to her, and kissed her softly. "Even covered in spit-up you're still gorgeous…" he whispered, and she blushed. "I'm going to try and put this little one to bed. I have some shirts and sweats in the go bag in my truck, my keys are in the front hall. Why don't you go grab them and get changed? I'll be back in a few," he suggested.

When he returned, Penelope had changed and was lying on the couch, her arm flung over her eyes. He approached, and lifted her legs up to sit beside her. "They're both asleep, and Michael's fever is gone. We did it!" he grinned, running a hand along her calves. Penelope lifted her arm just enough to throw him a look, to which he laughed. "What?"

"How are you not exhausted?" she asked him, yawning.

"Oh, I never said that," he followed her in a yawn, and settled beside her.

She watched him, wondering. This was a terrible idea, she thought to herself. There's no way he'll want to have kids after tonight… Terrible, terrible idea… why did you agree to this? She scolded herself, trying not to pout.

More to come for our favourite couple, let me know what you think!
