Team Gōketsu was in the middle of thoroughly sweeping their chosen room for seals and Kozo body-bits when Hazou got a much better idea and paused. "Noburi, would you be willing to go ask one of the Hyuuga if they'd be willing to check all the rooms?"
"Hm. Good call," Noburi agreed, heading to the door.
"AAAAH!" he shouted not five seconds later.
Hazou and Keiko were through the door before either of them even realized it, kunai drawn, directional explosives pointed opposite directions down the hallway. Hazou happened to be facing away from where Noburi had walked, and so heard rather than saw Noburi fall to the ground, his forehead protector actually doing its job for once as it slammed against the polished wooden floor.
"P-please accept my apologies, Lady Hyuuga!" Noburi stammered.
Hazou blinked, and then slowly lowered his stance and turned to look at his friend. And now brother, actually, he mused. Noburi was on his knees in front of a half-open door, the visible part of his face rapidly approaching potentially dangerous levels of blushing.
"Oh, ah, sorry, give me just one second!" came Hyuuga's voice from inside the room. A couple of seconds later she opened the door all the way, wrapped in a towel that looked so luxurious that Hazou could feel his wallet getting lighter just looking at it. "Is everything alright, Gōketsu?"
Noburi sat up slightly, still looking at the floor. "I'm really sorry, Hyuuga, I didn't mean to invade your privacy. Inuzuka and Aburame didn't mention you'd be changing, it didn't occur to me to knock."
She waved away his apology. "Ah, please don't worry about it! The Byakugan means we Hyuuga tend to... care less about privacy, for various reasons."
As Hazou digested the implications of that statement and resolved to move mobile versions of the privacy seals as far up on the research queue as possible, Hyuuga looked over the still-armed ninja in the hallway and asked, "Did you need something from me in particular, or...?"
"We, uh, we were hoping you would be willing to help us sweep for seals around the barracks. And also eyeballs and ears, there's a Mist clan, Kozo, that can detach parts of themselves and they like to use that ability for spying," Noburi explained, finally starting to stand up and looking absolutely anywhere except the girl in front of him.
"Oh, yes, of course," Hyuuga answered, nodding. "My cousin and I did a sweep as soon as we all arrived, and neither of us spotted any seals, but there was a young man up on the roof who had suspended an eyeball with his own chakra in it on a piece of twine. He was moving it around between windows, so we figured it was some kind of scouting technique." Her expression darkened. "I had Kiba grab it when it got to our room, he and Shino are off to see if they can find anything fun to do with it. Kozo, huh? Good to know."
Hazou didn't bother to suppress his shudder.
"Anyway," Hyuuga continued, suddenly brightening again. "I was off to take a real bath instead of the field wash we had earlier, and I just realized I need someone to pair up with to follow the Hokage's order about staying in pairs. Would you be willing to go with me, Gōketsu?" she asked, looking at Keiko.
"I--wha, HUH?" Noburi blurted out, his head snapping toward Hyuuga. She glanced at him silently for a second, looked briefly over at Keiko, and then looked back at Noburi, before starting to laugh.
"Sorry! I don't mean to make fun of you, I suppose that was bound to get awfully confusing," she said, still giggling. "I know we haven't known each other long, but would it be alright if we used each other's first names, at least when you're all together like this? Just to make things simpler."
Noburi nodded mutely, as did Hazou. Keiko hesitated, and Hyuuga immediately threw up both hands toward her. "Ah, please don't worry about it if you're uncomfortable with it! And anyway, if the boys are okay with first names, then it'll be clear who I mean when I say Gōketsu, so it's fine!"
The aforementioned boys had immediately found very interesting things to investigate up on the ceiling. Keiko looked down at the towel that Hyuu-- Hinata had dropped in her gesticulating, and raised an eyebrow. "I'll go get changed as well, I suppose," she said simply.
