The casting call for the adult calls for "Someone in their late-20's to mid-30's". IF (and I will say again that it is still a big if) this is in fact an adult Henry with Robyn, then the age range could just be there to throw off people would are smart enought to determine that Henry would only be 23. They could easily find an actor that could play a person in the indicated age range, but could also play a character in his early 20's (not that big of a stretch). What will probably be really telling is when they announce the actor, since they do have a good track record of picking age apporpriate counterparts for their characters. The same is true for the 10-year old, I could see them finding some girl that could easily pass as the daugher of Zelena and Robin Hood.

But all of that is only if the guess of Henry and Robyn is accurate. it could be something else entirely (heck, we didn't already have Jefferson and Grace, I'd be pulling for a recast of their characters.)

As for them saying that the new character is a leading male, that really only implies that the character would be joining the main cast, and says absolutely nothing about the status of the rest of the main cast. Emilie joined the cast as a leading character in season 2, as did MRJ and Colin in season 3, Michael in season 4, and Bex and Sean in Season 5. None of those additions changed any of the other leads on the show. I don't see this as any different. If the other leads change, it is because of something related to their characters, not because they have a new lead.
