Prompt 2: Castle and Beckett go shopping for Kevin and Jenny's baby.

(Kate)

Kate was humming softly, sifting through a selection of onesies featuring dinosaurs, trucks, and wild animals. Jenny had excitedly let it slip to Kate that they were having a boy, but had made her promise not to tell Ryan. She wanted to surprise him with the news at the baby shower.

"Kate! C'mere, you have to see this!" Castle's excited voice sounded from a few aisles over. She scanned her options once more, and picked out a few outfits before heading off to join him.

She found him down an aisle marked "Seasonal/Specialty". She suppressed the urge to roll her eyes. Of course.

"So Castle," she said, leaning against one of the shelves. "What was it that I needed to see?"

He held up his find with a triumphant smile. "Awesome, right?"

"Castle, no," Kate protested. "There's no way in hell we're getting them that."

His face fell immediately. "Why not?" he asked, pouting.

She sighed. "Because, Castle, we're just not."

He unleashed his puppy eyes on her, full force. "But it's so cute," he argued. "And it's really soft. Feel it."

Kate reluctantly took the romper from him, rubbing her thumb over the fleecy fabric. He was right, damn him. "But still, 'Kiss me, I'm Irish'? Don't you think it's a little cliche?"

Castle shrugged. "Well, yeah, if I were buying it for Ryan," he said. "But this is for Baby Ryan, so anything cliche automatically becomes cute."

She glanced between Castle and the romper a few times before handing it back to him with a sigh. "Alright, we can get it."

"Really?" he asked, a beaming grin spreading across his face.

Kate laughed. "Yes really, o' man child of mine." She glanced at her watch, then pushed off from the shelves. "C'mon," she said, hooking her pinky through his. "We're supposed to be meeting Alexis and Pi for lunch in half an hour."

His thousand-watt grin dimmed a little. "Right. Pi," he muttered.

They were almost to the end of the aisle when something caught Kate's eye. "Oh, Castle, look at this," she whispered.

She held up a navy blue romper with the words "Daddy's Favorite Ride-Along" across the front. NYPD was stenciled on the back, and the bottoms of the feet had badges on them.

"That is the most adorable thing I have ever seen," he said. "Is there a 'Mommy' one too?" he asked, leaning over to check the shelf.

Kate stepped in between him and the shelf. "Seriously, Castle?" she said, raising an eyebrow.

He just grinned and reached around her to pluck one off the shelf. "Ha, found it," he said, holding it up to show her. "This one's even cuter, isn't it?"

"Yeah, it is." Kate took it from him, gazing at it wistfully for a few moments before putting it back on the shelf. Before she could change her mind, she pulled out her phone and snapped a picture.

She looked up at Castle, who was staring at her with a mixture of adoration and confusion. She grinned shyly. "Future reference, Castle."
