...I feel like this scene is particularly "worrisome" in terms of what Jason's "secret" is.
I think it's just really, really, really frustrating that DC seems to want to make so much unhappiness for Jay. I mean... C'MON! No wonder why the guy needs some serious therapy.
Let's see: a) Dad abused him b) First mom died, OD. (Didn't he nurse her for a year on the streets or something?) c) Survives on the streets d) Becomes Robin and then all he wants to do is FIND HIS REAL MOMMY e) "Disobeys" Batman coz he's an impulsive teen (OH NOES! HE SHOULD DIE FOR THAT) and gets betrayed by real mommy and beaten to death and blown up by the friggin' Joker f) Comes back to life to find out the Joker is STILL AROUND AND STILL KILLING AND MAIMING PEOPLE AND THAT BATMAN NEVER AVENGED HIM g) Tossed in Lazarus pit by Talia and also made out with her, which may or may not be a good thing.
And yet on top of all this, he may or may not have this secret that may or may not be related to this talk he had with Mia about them being cut from the same cloth/possibly going thru the same experiences (Jason forced into prostitution as well?)
