Recently I caught the last page cameo from Jason in another book. There was a detail that reminded me of other appearances prior to the New 52/DCYOU.
SMALL SPOILERS FOR A RECENT COMIC AHEAD
When Jason meets Wonder Woman in For the Man Who Has Everything he's noticeable cold. This prompts Diana to comment which brings up the infamous exchange with Batman and him. It makes sense though because his costume--rather Dicks' costume--left a lot of visible skin. It's not ideal for working in harsh winter environments.
This come into play again when he first joins the Teen Titans for a mission and comments on his uniform being less than ideal.
At the end of Batman/Superman #25 Clark has this greet him. What stuck out? The fact that once again Jason is freezing despite the fact he's protected against the elements. Now I brought up something along these lines before when discussing some of Jasons' abilities. In RHATO #5 all the leads fall into the icy water with Kori unaffected because of her powers. Roy is noticeably cold and his teeth are chattering to the point it effects his speech.
Jason jumps out and seems utterly unaffected by it.
Is he just faking it ? I know I'm overthinking this, I do that with these details.
