"Hey, Grimmjy-tan?" Grimmjow scowled and glanced down at the small, green-haired Arrancar at his right.
"What?"
"Well, Nel wath talking to Ithane-tan, you know, from Fourth divithion, and the thaid that a baby'th hair colour dependth on the mommy'th and the daddy'th, and that they thometimeth mixth together, and you get the baby'th hair colour," she articulated, and Grimmjow noticed that she had yet to get over her lisp. "Tho doeth that mean that I'm you and Wonder-tan'th baby?" Grimmjow spat out his sake in shock.
"What the hell? Hell no! Like I'd ever even touch that creepy little dude. And besides, he's got a girlfriend! Ichigo's little sis, remember? What's her name, Marin, Karin? Yeah, that's it, Karin. And I've got a girlfriend too!" Nel stared at him in awe.
"Really?" she cooed. Grimmjow scowled.
"Of course! Hot hunk-a manflesh like me, the girls are practically lining up for a piece of this!" he boasted. Nel, looking stunned, held her hand over her forehead to assist her sight and peered down the lane, searching for these fabled lines of women. A tumbleweed rolled sleepily past.
"Nel doethn't thee them," she pointed out, giving him a doubtful glance. "Maybe they all went for thome coffee?"
"Not literally, Nel no Baka," he growled. She pouted up at him.
"Nel ithn't a baka! Grimmjy-tan ith a meaniepanth! Nel liketh Itsygo better!" He growled angrily. Gods, what the hell had he ever done to deserve this? Oh, right, years of service to the most evil bastard the world had ever seen. That's probably what did it.
"Tho, getting back on track," - and here she frowned at him, like it was his fault they had changed topics. Which it was. Whatever. - "Why aren't Grimmjy-tan and Wonder-tan Nel'th parenth? They hath the right hair colourth."
A tick was developing in Grimmjow's eyebrow. "Think about it this way. Is Yachiru Ukitake and Abarai's daughter?" Nel looked shocked.
"Ohmygodth, maybe the ith. It'th Nel'th patriotic duty to tell her about thith!" Nel scampered off, eager to spread the gossip, and Grimmjow pondered whether he really wanted to fight Zaraki Kenpachi right now, without his sword. He decided it would be prudent to arm himself - not that he couldn't take him, you understand, but It never hurt to be careful, went to collect his blade.
Fifteen minutes later, a howl went up from Eleventh. "I'm gonna kill 'im for this! Where is he? I'm gonna kill that damn Arrancar!"
