Arcane headcanons them reacting to you coming from another universe
However you got here, why, or who or what you are is unknown to him. All he knows is that you're here and you're from another universe
Unless you're a dangerous lunatic or something, I feel like jayce would talk to you
He'd be wary af ofc. He'd come to you like you go pet your friend's dog after they said it doesn't bite
So, like you're a wild animal of some sort
I mean, it's a different universe! Maybe there's like aliens and other stuff like that there? Or maybe it's his nerd brain overwhelming with possibilities
So yeah, he'd ask questions about your universe. Like how it's like or the people there. And then some ridiculous questions about science ofc-
Hey, ik I'm saying ts a lot, but this guy is an absolute nerd. People just don't think that because he doesn't look like one but he IS
He'd make an embarrassed laugh if you side eye him, and would be over the moon if you were matching his energy
But let's be fr, that man can't really keep a secret. If people didn't know you're here before, they probably do now
He'd talk about it with Viktor and Mel- asking for their opinions
Yes, we know he's like that
Viktor would be fascinated for sure
He always loved science, and discovering. Now? This is revolutionary to say the least
How did you travel to this universe? Why? Who or what are you? Is traveling universes common in yours? Actually, how's your universe like at all?
So yeah he'd have a lot of questions to ask, but he doesn’t sputter them out carelessly of course
Viktor feign indifference, but he'd definitely be so interested. Take the scenes where he's interested in jayce in season 1 act 1. Yeah, it's like that
Like with jayce, he'd approach you if you're not a dangerous lunatic. And even then, if you were, the guy would be set on talking to you
Be prepared for him to bring his notebooks. He absolutely wants and will take notes about you while asking you questions
I mean of course he wants to study you, he's a scientist
If you get mad at him taking note, he'd momentarily stop and look at you. Even without saying anything you can feel the sterness
"This could be revolutionary and you ask me not to take notes?" Sarcastic, of course
He'd find it ridiculous- like dude he needs to take notes
He'd get into scientist/work mode, completely forgetting the rest until he solves it tbh
Oh oh now that'd be messy
Jinx does hear about you but she doesn't seek out to you at first
What! She has other things to worry about, yk?
But when she meets you she does tease you about that
"Ah! If it isn't the little traveler!" Somehow she makes it sound both energetic and threatening, like you never know how she will react next
If you're against her, she'd probably try to kill you ngl
But if you're neutral or something like that, now she'd have some fun with that
If you have powers or whatever, something that can benefit her, she'd try to make you join her
If you're reluctant jinx would probably just annoy you until you caved in, and would probably not like that
She'd try to make you visit zaun, commit some crimes, blast music while showing off her gadgets-
Ofc jinx doesn't trust easily, but it doesn't keep her from having fun right?
Like jinx, when vi hears about you, she doesn't care much at first. You kinda get used to hearing all sorts of things in zaun
I mean it's not really the first thing she worries about considering everything that's happening
She'd be more interested though if she hears about something that could be useful to her
Ex if you're like an amazing fighter, scientist etc
Then she'd come up to you. Don't ask how, she will just do
The fighter does find you though, jumpscaring you
I feel like she'd either surprise you out of nowhere or have been waiting for you in your hideout. Either way, she's here now
Whether you're threatened or not, she'd be smug
"So. I heard you'd be quite useful. Honestly when I heard someone traveled to this universe, I thought I had heard enough bs for a month. But, here we are"
Wouldn't outright ask questions about your universe, but would tease you about that
"What, you don't got that in your universe or something? Come on, get going"
She does help you blend in here, even while teasing you
