Canon
Kid Flash and Jinx met in the episode "Lightspeed", where Kid Flash never failed to flirt with her whenever the two were alone. However he saw good in Jinx and wanted to help her, Jinx took advantage of this and instead captured him to hand him over to Madam Rouge, to help Jinx and her team be seen as serious villains. However Kid Flash escaped and was tracked down by Jinx who was actually Madam Rouge, when he finally managed to escape her the real Jinx showed him and imprisoned him with one of Gizmo's gadgets. When Madam Rouge turns up Jinx happily said to her that she captured Kid Flash, but Madam Rouge hits her and tells her it was because of their fight earlier that has slowed Kid Flash down, allowing Jinx to get him.

Angered by not getting respect Jinx let Kid Flash go, angering Madam Rouge but Jinx doesn't care about her anymore and walks away. She see's a red rose in a vase outside and picks it up, she see's Kid Flash run from the corner of her eye and smiles.

They are next seen in "Titans Together" where Kid Flash taunts the H.I.V.E 5 for joining the Brotherhood of Evil, he apologises to Cyborg that he is late and stopped to pick up a "friend" - meaning Jinx, who smiled at the speedster.
