Ask for Goodbye's tips on how to treat the other girls (Time -1)

At your question, the lady's shoulders shot upward and her fists hit the table hard enough for drops of her coffee to spill out and onto her papers. Instead of addressing her obvious paranoia, Goodbye slid her glasses back up the bridge of her nose and answered calmly. "Th-That's really more your task than mine. I try not to fraternize with my subordinates, so I don't know much about their lifestyles. But don't all girls want to be treated well? I-I'd recommend just, you know, treat them kindly. Try not to piss them off. Try to be a gentleman. Act like James Bond, but without the sexual harassment. Well, with the harassment, but only when they can't tell it's you and it benefits you filling out those dossiers."

You told your boss that seemed like some pretty shady advice.

"Don't document that in my dossier! In fact, stop filling out that dossier- I never asked for you to fill out mine!"

You told her you were only being dutiful. Nobody was beyond suspicion, not yet.

"Hrrrgh..." Grumbling, she took another draw of coffee, which seemed to somehow even up her mood, even while making her leg twitch harder underneath the desk. "Fine. I'll tell you what I can. First off, there's Tschau. As a ninja, she carries all sorts of poisons and deadly ninja weapons, like a ninjato- a short sword. Sh-She hides in the dark, even when I talk to her, and she threatens to kill me all the time if I do anything that obstructs her code of justice!!" The woman's voice had become shrill and fearful at the end there. "Don't ever ask her about her height! And don't ever try to look at her phone!"

Sheesh... It sounded like Tschau and Goodbye were on pretty bad terms. On the other hand, it sounded like maybe the ninja wouldn't be so bad, as long as you didn't invade her privacy... but you were going to need to be pretty invasive to get anywhere.

"Next is Despedida... She acts friendly, but as a huge, big-shot video gamer, she'll crush you without a second thought! Even if you're just learning the game! And then you'll never want to go to company game night ever again!!"

That didn't sound particularly dangerous... But it sounded like Goodbye wasn't good friends with her either. You urged her to continue.

"Vaarvel is the scariest of them all... she's been a Goodbye Girl longer than anyone and yet I know almost nothing about her!" You felt like pointing out that it didn't seem like she'd made much of an effort. "Sh-She can disguise herself so well, I hear she's even impersonated me from time to time... That's identity theft! CEDIT does not look kindly upon that sort of thing!"

That tall, slender black lady was impersonating the whitest, short-stackiest woman you'd ever met? This you really wanted to see...

"And Au Revoir... no, I take back what I said earlier! Au Revoir is the scariest of them all! Those huge arms... That booze tolerance... That scary smile... J-Just don't talk to me about her! Uwaaaah, I want to go home!" the boss sobbed, suddenly diving underneath her desk. "Take my calls for the rest of the day! Tell everyone I went home with a tummy ache!!"

... Well, none of this information had been very helpful. All you learned was that your boss was even more afraid of the Goodbye Girls than you initially sensed. You stood up, politely excused yourself, and then left to do some digging on your own...
