She mutters under her breath to him while they have a moment alone. "You're a terrible actor." He flat-out ignores her and continues to fake-ramble about ramen.
She jabs the needle into his arm extra hard.
He's so extreme that they're getting nowhere. If she were the patient this time they would have been making more progress…unfortunately she was an actual doctor and it's easier to fake mental illness than papers these people will accept.
Plus, the person administering the psychotropics also needs to be able to make untraceable antidotes, and that's hard while high as a kite.
He's kind of cute sometimes during the time between administering his dose and then curing him of it so he can pretend to gather information. She's pretty sure he's just reading or something, and it's not needles she'll be stabbing him with if she can confirm that.
He's cute and occasionally off-puttingly affectionate when he's high.
She has literally no idea how he managed to stumble across what they were looking for while fake-playing hopscotch with Kiri nin, but she knows he's lying through his teeth when he claims he planned it.
Getting a needle full of psychotropics jammed in her arm as unkindly as it just was…sucked.
Surprisingly, he actually paid enough attention to figure out how to synthesize the antidote she was out of (though not the untraceable nature she'd achieved) while he was pretending to be a bat one of those times.
They reached an agreement by the time they made it to Konoha: He wouldn't talk about any nakedness she displayed while high, if she didn't tell the Hokage that he sang dirty versions of nursery rhymes while he was high.
It was the smart thing to do.
The Hokage probably would have filled them both up full of needles if she'd known anyway.
