Title: New parent panic
A Shinobi's life often depends on knowing more than the enemy. Intelligence gathering was a skill a shinobi had to have, as well as the skill to use the information collected at the right time. Most shinobi also developed an ability to bluff and pretend they knew more than they actually did about something so their interlocutors accidently spill secrets.
Every shinobi developed a network inside and outside their country so they could complement the data provided for a mission assignment with the data they personally collected. They could also know all about their comrades and evaluates the competition to rise up the ranks or to avoid to be relegated on the Bingo Book's last pages. That network also serves to propagate false facts and rumors about themselves to hide their strengths and weakness.
Even the civilians know that fact about shinobi. After all, they even have an old proverb saying: "To bait a shinobi, better use gossip than money".
…
Author's stage whisper: Or, at least, that's the justification most shinobi use to be unrepentant gossips. But anyway, let's resume this story.
…
Of course, the more a shinobi became known, the more rumors about him were circulating and the more all his doings were scrutinized. That's especially true for a Kage.
So, when Minato was heard one morning talking to Tsume Inuzuka about children, by noon all Konoha knew that the Hokage and his wife were expecting a child. Suddenly, civilians deserted the street and gathered in pubs while shinobi converged on the super-secret training field to exchange info on who heard what from whom and when.
After a moment of recalling all the bits of contradictory rumors floating on the grapevine, Konoha's shinobi agree that Kakashi Hatake was the best person to interrogate, err ask, to learn the exact truth.
…
When Kakashi came back from jutsu practice in a secret training field (a really secret that one, not the super-secret that everyone knew of), he feels scrutinized from every angle and his paranoia rises, especially when several people (civilians and shinobi alike) begins to accidentally cross paths with him and innocently (which was suspicious in itself) ask him how were the Hokage and his wife. With each question, Kakashi feels more dumbfounded and then more and more worried that he miss something big while training.
The mystery was revealed when Genma decided to take the forward approach (although, the first half of the conversation only further confused poor Kakashi and frustrated Genma):
"So were you in the know for Minato-sama and Kushina-sama?"
"Maybe." (As said previously, most shinobi default on bluff to maintain their reputation of super-spy)
"Great news, isn't it?"
"Sure."
"Although, I imagine some things will need to change to free Minato-sama's schedule."
"Hiraishin is always useful to gain time."
"True, true."
"…"
"…"
"…"
"So…"
"Hmm?"
"What do you think of it?"
"What do you think I think of it?"
"Kakashi…"
"Genma…"
"Oh, for the Sage's sake! Will you just tell me what you make of Minato-sama becoming a father!"
"…"
"Don't pretend you don't know! Everyone know he'll tell you first!"
"… What did you hear exactly?"
"Fine, fine, if you want to know, Ibiki heard from Anko who heard from Gai who heard from Ebizu who heard from Raidou that Minato-sama was asking Tsume Inuzuka advices about children's names! So, what do you know about it? How far along is the pregnancy? Do they wish for a boy, a girl? Do they disagree? Give me something so I can finally win a bet!"
"…"
"I'll own you a favor if you gave me premium facts."
"You know Gamabunta?"
"Minato-sama's summon?" (It was Genma turn to became confused)
"Gamabunta's wife is pregnant and they want to name Minato-sensei godparent."
"WHAT!" (With that simultaneous yell, Konoha's entire population step out of every nook to stare unbelievingly at Kakashi.)
For his part, Kakashi had raise his forehead protector and used the sharingan to memorize every incredulous face.
