Fan Casting Selina Kyle-Wayne in Batman: The Dark Knight Begins Again

At the beginning of the film, we see a flashback to the first kiss between Bruce Wayne and Selina Kyle, his future wife. Later, after Bruce finally escapes the Phantom Zone, he learned what happened to Selina while he was gone. In the final battle against The Batman Who Laughs, her flesh wounds were infected by Kryptonite shards from his chains that caused a rare type of cancer to spread. About six months after the end of the war, Selina died from this cancer, and was buried next to her parents-in-law, brother-in-law, and adoptive son. At another point in the film, we see Bruce visiting her grave and promising his true love he will honor her in the best way he can.
