Jinx and Melanie Walker/Ten
I feel like if Jinx accidentally got traveled into the future and she met Melanie they would get along so well.
Obviously, they would both would be on guard with each other, but if they take the time to talk they would understand each other. They both came from a past where being bad is all they know and grew in toxic environments. Deep down or subconsciously they knew what they wanted, but they didn't feel like they could; as Jinx believed she was bad luck and Melanie doesn't want to let her family down or leave her family. They would probably give each other life advice and tell how they broke out of that toxic environment. They can relate to how long it took for them to break out of the toxic cycle and finally do something they've always wanted, not just because of others. Also, I think in the background Terry and Wally (Kid Flash) would chat and play video games while the girls talk, pfft. Though I feel like if Terry were to talk about his previous relationship with Melanie and his current one with Dana, Wally would probably tell him that even if Terry has to keep his hero identity a secret, a partner should be able to understand how he's busy now and sometimes plans will cancel unexpecting. Wally would talk about how it took Jinx a bit to stop being a villain and how she knocked him out with a wet floor sign and tried to turn him in to the Brotherhood of Evil. Their relationship began a bit rocky (from screenshots I've seen in the comments, correct me if I'm wrong), but it worked out in the end. This might get Terry to reflect about his romantic relationships then. (P.S: I know Dana's reasoning to get mad for Terry is valid, but I feel like the writers should have shown a healthy breakup rather than keep them together as their relationship was on and off or really rocky. The only time Dana was seen to be understanding was a scene with Max where she came with the conclusion that Terry sees Bruce as father figure. That was about it and we don't here anything about them, until one of the episodes in Justice League Unlimited where it showed older Terry planned to propose to Dana right after she learned his secret identity.) Overall, Jinx and Melanie would get along and be besties because of their past and upbringing. Also, even though Terry does act like a high schooler, him and Wally would give off Batman and Flash from Justice League and Justice League Unlimited vibes.
Honestly i don't even think you'd need Jinx to travel to the future for that, by the time the future comes Jinx would probably be in her what, late thirtys early fourtys? Honestly i think Jinx could probably become something of a mentor or inspirational figure to Mel if they ever met
