I would love to know who her sister is, some more background on jinx in general too. Maybe she will be a champ in the future? Idk how you can get much more crazy than jinx though!
AzureInTheDark7 votesI believe in the past that Riot said that almost every champion has a brother or sister of some kind, save for some characters like 
ect.
I'm just saying, that if 
had a sister, I would surely milk those.

WHAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAT? VLAD HAS A SIBLING???
And, well, calcium's important.
TurquoiseYoshi4 votesI believe the only other champion who mentions a sister in anything is Vi. Jinx and Vi are supposed to be opposites. I assume Vi is Jinx's sister, but we know what they say about assuming.
Deep Terror Nami5 votesIt's also possible that she just has multiple personalities, and she has a crazier one XD
GenoXx3 votesActually...they are not sisters. It's clear Jinx ddnt meet Vi til she went in piltover. Jinx knew her sister and she's from zaun now confirmed. Vi on the other hand is said to have a sister, hinted by Lyte on the Howling Abyss. He also said she looks like her, and her and jinx look nothign alike.
TurquoiseYoshi1 votesSo now we have two people with unknown sisters. Greeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeat.
Dezudekiddo1 votesWell actually it's confirmed that Vi is ALSO from Zaun, and maybe Lyte is just blind or sumthin haha lol.
GenoXx1 votesBlind? Why do you say that?
GreenLore2 votesWell Vi has amnesia and it looks like VI was born in zaun. it is possible that jinx went to piltover without knowing anything about VI,but then she recognized vi,because of VIs tatoo(she had that tatoo since she can remember). I mean jinx seems oddly focused on VI,so it is possible that Jinx recognizes VI as her sister,but VI doesn't recognize jinx.
However you have a point about Lyte mentioning that Vi and her sister look similar,I mean jinx was pretty much designed to not look like vi. But there are ways around that(maybe Vi has only a very old picture of her sister,I mean jinx could have changed a lot in terms of appearance(its been confirmed that her hair&eye-color aren't natural),or Vi could have a not-blood-related sister in piltover).
I still think the female mechanic that riot tried to get into the game(twice) is planned to be related to vi.(originally Vi was going to be a female mechanic,later on Braum was originally going to be a female mechanic,so Riot still wants to add that character).
GenoXx1 voteslol, Greenlore I do not think they are sisters. That heavy rumor is spread apart now these days. They look nothing alike. Lyte insist VI looks like someone else. They would have to favor even in the slightest for that to be said. Jinx knows what her sister looks like with clear thoughts. "You think I'm crazy? You should see my sister." That speaks from a clear thought, not a hazy almost can remember one.
I still yet don't know why she targes her, but Gypsylord insist theres a reason. However, Ekko reveals shes from Zaun. Jinx could still remember VI, maybe as an old friend or aquaintance. But the sister rumor is too overated and believeable by most people. Just because one person say that "Hey if they both haev a sister, it must be them both!"
I would have this rumor seized from thoughts.(Spartacus rubbed off on me)
GreenLore1 votes....I just gave you 2 examples how the quote "Vi you look like your sister" could still fit even if Jinx was Vis sister(either that Vi has a non-blood-related sister in Piltover or Jinx has changed a lot in terms of appearance and Vi only has a picture of how she looked in the past)
Also like I said,jinx might be fully aware that Vi is her sister(the tatoo on Vis cheek would make it easy for Jinx to recognize her),its just that jinx doesn't tell it Vi,there is no "hazy,almost can't remember",because Jinx still knows Vi how she is in the present and she thinks that present VI is insane.
In the end I am not even saying that this theory is right,I am just saying that it is not out of question either.
GenoXx1 votesIt's the one you seem to be sticking to also
GreenLore1 votesNot really,its just that there isn't much to discuss about their sisters aside from the possibility that the 2 might be sisters,because there are barely any other candidates.
The only other candidate(and I think this is the most likely one,which I mentioned already above) is the female mechanic(at least for Vis sister).VI was originally planned to be a female mechanic,later on they mentioned that they once tried to make a female mechanic with a robot as a pet(not sure if said concept was the one that turned into vi) and later they tried to make a female mechanic with a large mechanical shield,that turned into braum eventually. The female mechanic being Vis sister would be a fine nod to Vi originally being planned to be the female mechanic and would explain the origin of Vis engineering skills.
dramatic banana1 votesThere is no way they are sisters, they were in the same gang, Vi is mentally stable-ish,Vi's sister looks like Vi and I'm pretty sure 
Don't look similar.
GreenLore1 votesPlease read what I write yeah? I just wrote 2 possibilities that could explain the "you look just like your sister"-quote and even talked about how the person above ignored that....
Also like I already said before VI lost her memories and now fights on the side of the cops which could be seen as crazy from jinx perspective.(also there is the possibility that they have another sister)
CasterGilgamesh3 votes is sister
ilt2 voteshave you seen Annie? that bitch is crazy
ThatHaleState2 votesVi has been confirmed by riot lore writers to not be jinxs sister. Otherwise I would not be asking this question.
RogueWill2 votescan you link me to that statement? Because last time I heard a comment for riot the neither negate it neither confirm it, they gave a vague response like when you ask if 
is from the shadows islands.
Also teh youtubber that voiced Vi was asked in one of teh conventions that if she would Voice Jinx and she mentioned she woulnd't voice Vi's Sister right before jinx release.
RogueWill2 votesHer sister is most likely but you will never hear a confirmation of Riot since is part of their mystery. (same thing with being from the shadows island and riot never confirm it neither negate it). Even the shopkeeper on aram ask for Vi's sister, oh wait! he is not supposed to talk about it.
Maratsune2 votesI honestly believe that Jinx and Vi are sisters. There are too many parallels between them, and too many mentions of either one's sister, for it to be a coincidence. If, one day, it's 100% denied, then I'll be a little sad because of wasted potential.
Desiloth1 votesI always hear "You think I'm crazy? You should see my sister" So I always thought that Vi was her sister since she is quite the crazy chick and they went into 2 different life styles.
SlackerboyTC1 votesThje question is when they will add said sister to the game
ModAcademy Kayn1 votesI'm pretty sure its just a joke saying, but who knows.
Matezoide1 votesDidnt Phreak and Jatt say during a LCS match that Vi is her sister?
Then again, they also said Rek'Sai is a Male, so take that with a grain of salt.
Baunjo1 votesim gonna have to go with 
or 
. could be wrong tho
