I feel like Celine has a lot of odd little quirks that only Bobby and the girls really see or know about, and the girls (especially Rumi) are completely used to it but Bobby finds them really funny/cute/charming. Like talking to appliances.
She'll say things like "it's okay, you can do it! You've done this before you can do it again!" to the printer, or "I don't think this was your fault" to a coffee maker in response to a really bad cup of coffee. He's seen her pull what appeared to be a slab of charcoal out of a toaster and say "wow. I can't honestly tell if that was an accident or if you were trying to make a point." She'll sigh and shake her head at a beeping smoke detector and say "all you ever do is complain."
And this doesn't phase the girls much because they're a bit more familiar with her softer side but Bobby finds it incredibly funny that he's caught his scary-as-hell CEO boss talking to her laptop like it's a scared horse
Which Celine are we fucking talking about I have multiple AUs involving her. Monachopsis Celine might act like that because Rumi drives her insane though, but I don't see canon Celine acting like that, at least, mostly. Maybe a bit sarcastic.
She'd probably say the smoke detector part tho lol, along with the toaster part. I feel like she has a bit of sass like Rumi.
HOWEVER, Reincarnated Celine definitely says those, albeit more flat and deadpanned instead of saying it with emotions
Anon is this Bobbyline please tell me your ask is Bobbyline please please please I am gnawing through the fucking cage
Okay I'm going to just talk about Reincarnated Celine.
She talks. Like, not like Zoey, but she definitely talks. You'd hear her sass someone out and when you look at her it's either no one or someone who was being a bitch, it's 50/50. Either her hallucinations by Gwi-Ma or a real person infront of her.
"Oh I can't believe you've done this" was said when the elevator jammed and both Celine and Bobby were inside and she was yelling at the button (she was angry at the elevator).
At some point she glares at her coffee machine that randomly stopped working infront of Bobby when she was trying to make him his coffee and talks to it angrily lol.
Bobby sees all of those talking as adorable and cute (sometimes a bit concerning, because R!Celine literally fucking hallucinates), yeah his CEO is fun to work with despite being a literal demon against corrupt people
R!Celine has more quirks than that, but half of it is... pretty concerning, but only if you're not HUNTR/X or Bobby. Actually wait no Bobby is also concerned.
