I don't think Vi leaves Jinx on the bridge for Cait, she leaves because she can't stand what Jinx represents when she's goin crazy and Vi needs Caitlyn to get anywhere in the city. It is made abundantly clear by the end of the series that Vi wants Powder back and sees Jinx as not who Powder is now but as a manipulated damsel that she had to save. Jinx detests this assumption, even if she can't fully understand why at this point in the story and it is why she drops the name Powder forever in the last episode. Vi can't cope with the fact that she is the reason Powder is gone, so she makes up excuses for why Jinx exists and refuses to accept her for what she is. Which in the end makes her lose both. That is the whole point of the Vi Jinx relationship after episode 3, Vi won't accept Jinx and work with her, so she tries to punch her way back to Powder who she originally threw away. Jinx wants to be accepted, but is so broken that she just kind of gives up and copes as an insane lunatic.
I'm talking about the bridge scene where she literally abandons jinx for no reason at all.
This is the first time she has seen Jinx eye to eye since they were kids. When she saw powder/jinx on the bridge she had literally no reason to leave.
Even ignoring the fact that she has no reason to give a shit what happens to cait, cait could have gone with ekko, leaving HER behind instead.
She saw her baby sister for what is the first in half a decide and she decided to leave her to get beaten up by ekko just so she could hang out with cait who at this poitn she knew for less than a day?
There is literally no reason for her to not stay behind on the bridge. That was literally her last chance to show to jinx that no, she will not abandon powder, but she literally willingly abandoned powder in this case when there was literally no reason to.
Literally, what reason did she have to NOT stay on the bridge with jinx? Taking care of cait?
A.) Why does she give two shits about cait, cait is a cop she's known for less than a day.
B.) Leave cait with ekko and stay with jinx.
The Caitlyn stuff is pretty whatever though, she is by far the weakest protagonist and LoL Champion here and the Caitlyn/Vi ship that's been teased overtime since Vi's introduction is kind of a waste of time to explore given how late Caitlyn shows up relative to everyone else. Cait is implied to be understanding of just how wrong her perceptions of Zaun/Undercity are as she is forced to interact down there and with Vi during the middle section of the series. The romance is still kind of weak and Caitlyn is kind of boring overall though. Caitlyn is just unfortunately handled, which is funny to me as I thought Jayce would be more boring than Caitlyn when I first heard he was in Arcane. But Jayce is actually great in Arcane.
The cupcake nickname has been in-game since Vi's release back in 2012, if Vi didn't call Caitlyn cupcake it wouldn't be right to people who've followed her since release as a character. It is just a bit of fan service that is unfortunately handled due to how rushed Caitlyn is in general. I don't think Vi trying to kill Cait works, because that goes against what Vander wanted as Vi's stubbornness in trying to own the Upper city is what caused everything in this series to happen the way it did and in the end she just wants Powder back so wasting time trying to kill Cait is time wasted not saving Powder. Plus she gets to passive aggressively mess with the upper class pretty much for free, which is a nice plus.
Arcane rewrote shitloads of league lore to make the story work to the point of altering half the timeline. By the time jayce rolls around Camille and her family have been profixing off hextech for more than 80 years.
Not to even mention skarner.
"We must shoehorn in a gay romance where it doesn't fit because of the LORE" doesn't work when they're already broken the lore of several characters to make arcane in the first place and already said that its not canon to the main timeline.
Wait are you saying the studio legit threating the writers if there wasn't a gay romance going on?
I guess I could belive that since for majority of the season I belive them as simple friends until Jinx started calling Cait "Vi's girlfriend"
No, the writers wanted to shoehorn in a gay romance and the studio told them to fuck off.
