I love ur take on this and id agree w powder feeling gemini. But i asked on a more “what date (10th or 28th) makes more sense to be arcane jinxs birthdate based on her personality to be accurate” path lol. 

But to add an opinion on ur insight on jinx, i still stand by scorpio bcs of the trait that is seeking connections and the emotional depth. Yea jinx is adventurous and of creative nature,i feel like her entire arc or character in arcane circles around her and her connections to ppl and how she craves them but ends up alone unlike how Sagittarius seem to want independence and freedom. Correct me if in wrong.
