I thought about it.... Did she jsut happen to find Vi fun when she chased after her? Or did she already have that motive upon entering Piltover? As if they had some history before...
They do have history, they were in the same street gang in Zaun when they were kids. How every i dont think has the attention span to track down and follow Vi. She just wanted to cause chaos in a big city, just so happend that Vi was the police force in Piltover
i dont think Jinx
was just in her house one day. She was dying of boredom so she decided to go to piltover (Also really boring). She blew stuff up and for the first time, she was having fun. Nobody knew what she looked like until people catching glimpses of her. While she was fixing up Pow-pow, someone told 
and 
and they immediately went to search for her. When saw her she was just like "Mmm, OK girl you can't do dis" And she was waiting for to say something but she just looked at and nodded with agreement. The reason why she didn't want to say anything is because and used to be really close because they were in the same street gang back in Zaun along with 
and seeing her didn't make so happy, she wanted to switch sides because before, used to be a "bad-girl" like and she switched sides so she can still punch people for a greater good. She wanted to convince to switch sides but she knew it was impossible. She can't blow stuff up for a greater good. The next day, spray painted on piltover's most important building. It wrote: Hey fat hands or hat lady! One of you, come try to catch me at 3:30 today11 thought this was her chance. she chased her old friend until released a hell ton of rockets and a building collapsed over both of them (luckily, none of them died). When got out of what used to be a building, was gone. There was only one thing spray painted to the closest undamaged building. You'll never catch me!11 >:D
Hope this answers your question. You're welcome*[slayer-jinx-wink]*
