Sorry it took so long to get back, I swear I haven't disappeared on you, haha. But yes, I'm thinking that they've been working together for many years and are now a newly wedded couple recently moved to Metropolis? And I like that idea of a character or two knowing about him! He probably operated under a secret identity like most neighbourhood heroes and his former team members and/or people he cooperated with at some point will probably think he's either perished or gone rogue (the latter especially when they recognise his powers).
