Spitfire

Spitfire is a ship between Wally West and Artemis from Young Justice.

Canon
At first, they despised one another. Every scene with the them was an eye roll and a smile. Through season one they slowly warm to one another. And Wally was the most upset when Artemis got 'blown up' by a laser in the episode Failsafe. In Insecurity, Wally trusts Atremis, even standing up for her against Red Arrow (Speedy ) which sadly ends with that trust being broken when Artemis lies about tracking Chesire. Artemis was forgiven in the season one finale when she told that truth about Chesire. Later that episode Wally kisses Artemis and said; "I should have done that a long time ago." And she replied; "No kidding."

By season 2, they are still together. They go to colledge together and take the same courses.Wally disagrees when Artemis returns to become a hero for another mission, faking her own passing to work as a double agent with Aqualad (Kaldur'ahm) for intell. Artemis is away from Wally 60% of th season, (I did the math) but their connection with each is strong. In the season two finalle they are reunited once again. Kid Flash and Artemis go to Paris to defuse a bomb. Wally remarks: "Ah, ze Eiffel Tower and the ever romantic city of lights. We're definitely coming back here, babe, y'know, when we don't have a world to save." Artemis replies, saying back: "There will always be a world to save. Now drop me and go." Later that episode Wally dies from sacrificing himself to safe the world. (Or he ran really fast and ended in another dimenision, who knows!) Artemis mourns his passing and is comforted by M' gann/Miss Martian. Impulse/Bart Allen is wearing his new Kid Flash suit, Artemis tells him he looks good but Impulse admits he feels like a fruad. Artemis takes on the alter ego Tigress saying; "Artemis was Wally's partner. I need some distance. I need a change." Impulse replies "As a hero?" She says "As a blonde."
