Let's suppose that Selina Kyle decides to "retire" from that Catwoman thing, and marry a nice guy, and settle down to have kids and raise them with her husband.
Let's also suppose that Bruce Wayne is not the lucky man. Whom would you expect her to marry instead?
For instance, do you have a particular canonical "hero" or "villain" in mind as being especially well-suited to Selina, or just a general idea in your head of "what sort of guy would she be likely to pick if Batman wasn't on the market?" I'll appreciate any thoughts you care to share!
