Exactly What it Looked Like
(unless you're Iemitsu)
It was a simple fact that Reborn's training was effective. No one denied this. Say what you might about his methods, but they did leave a lasting impression.
On the up-side, this meant Tsuna didn't even try to shirk his paperwork. It was a sad day in reality when paperwork, which was generally tedious and boring, was considered a break, but that's how Tsuna saw it.
On the down-side, it meant his work ethic had morphed over the past few years into something that might have flipped from the 'lazy' end of the spectrum all the way up to 'overworks to collapse without proper supervision'.
Ordinarily, Tsuna's bizarre view of paperwork—although he admittedly didn't have as much as the Nono had, because Reborn had made sure Tsuna knew how and more importantly, when to delegate—made things easy. When he was sick, not so much.
He'd woken up without a fever and immediately decided to head to his office and start on the work he'd missed the day before. Of course, he'd been unconscious most of the day before, and not actually coherent when Shamal had ordered his Guardians to keep him from doing anything strenuous—'and that includes paperwork, you idiots'—for another three.
Reborn took it upon himself to see to it that the more rowdy factions in the manor were not going to get into trouble, trusting Ryohei and Gokudera to keep Tsuna from working while he was gone.
He got back to Gokudera freaking at Tsuna for not being in his room, Ryohei exclaiming about how 'not-extreme' it was to break the doctor's orders before breakfast, and Chrome wondering aloud why no one had told Tsuna he wasn't supposed to move around because he'd cause himself to relapse, all of which seemed to slip past his student's ability to focus on.
(Personally, Reborn thought no one had told him because he'd been sleeping, which he should still be doing, because Shamal giving bed-rest orders was exceedingly rare.)
And, of course, that was when the idiota showed up. It was no secret that Reborn didn't like Iemitsu. The only reason he hadn't already shot the man was because Tsuna had asked him not to, and he was Tsuna's blood, even if that didn't seem to mean what it should to Iemitsu.
Naturally, the idiota added to the mayhem in the wrong direction, being completely ignorant of both Shamal's instructions and somehow the air of the situation as a whole.
"Tuna-fishy!"
Tsuna, lacking his usual self-control and inhibitions towards violence due to obviously having reignited his dangerously high fever and thus being more loopy than someone completely smashed, immediately snarled at his sire, Sky Flames bursting to life in his hands.
Huh. And the only phrase had been 'Tuna-fishy'. Reborn had known he didn't like it, but that was some violent dislike. Still, igniting his Flames and moving to get in a fight with Iemitsu, who, for all his incompetence as a parent and husband, was a strong fighter—that was not bed-rest.
Reborn strode into the room, shooting at the current head of the CEDEF (he knew Tsuna was looking for a suitable replacement, and was pretty sure Lal Mirch was creeping up the list of candidates) before glowering at his no-longer-official student and snagging him by the forearm to make him hold still. "Flames off, Tsuna."
The instant the flames died, Tsuna wobbled.
Reborn caught him with a huffy growl, scooping him up into a bridal hold as it was quite clear he wasn't conscious enough to be heading anywhere on his own feet. "Dame-Tsuna, you're not supposed to be straining yourself. Back to bed."
Behind him, Iemitsu lunged with a indignant "Let go of my Tuna-fishy, pervert!" and he heard a heavy 'thunk' as Tsuna's available Guardians flattened the man.
"Juudaime's sick, you moron! Reborn's just putting him back in bed!"
"It is not extreme to attack Reborn when he's trying to help when Tsuna extremely has a fever! You should extremely not interfere!"
"Ano, you should let Reborn take care of Boss, or he'll never stay put. He only listens to Reborn when he's that sick."
(At least Tsuna's Guardians weren't complete idiots.)

*I had a wacky flu-strain like that once. I'd been out of school for a couple days, fluxuating between 103° and normal, and woke up feeling relatively fine one morning. Got up, got ready, walked out to meet the bus, and my sisters were asking me if I was sure I should be going to school by the time we actually got to the end of the driveway. I felt all right, so I insisted… and my morning teachers converged on me and herded me to the office at lunch, called my parents, and sent me home. Turned out I'd gotten all the way up to 104°, and I still felt relatively okay. Didn't look it, though, apparently, and wasn't, but I felt okay. Mind, I was apparently staggering like a drunk, and they didn't let me back in school without a doctor's clearance. _
