User blog comment:Rossendale2/A theory about Jinx/@comment-5924090-20131002001904

well lets get some lore in the line:

1- Thresh has nothing against Lucian, its said that Thresh stole Sienna's soul because she reminded him of his own wife.

2- Thresh only tortures those who he wants to capture, so far there is no clue that Thresh is lookng to fight Lucian, not yet at least.

3- If thresh could twist Sienna's mind enough to make her thing she is someone else then he would need to find her another body, wich he wouldnt bother to try.

4- Jinx is already Vi's sister wich means she is from Piltover or at least born in there (as so its said) and if Lucian and Sienna where a couple (dont point at me as racist just a guess) she would probably be black or at least ebony and they are also from Ionia wich is FAAAR away from Piltover/Zaun.

just saying
