New Information on The Graysons' Appearance on GOTHAM
Some new information has surfaced on the inclusion of the Grayson's in Gotham. A few weeks ago we learned that Robin's parents would appear this season, and now we have some details.
The news comes from TV Line, who says a casting call has gone out to agencies for John Grayson and Mary Lloyd. They are described as "teenage circus performers who will figure into Episode 16 and hint at the origin of a certain boy Wonder." Showrunner Bruno Heller previously had this to say about it:
“We’re going to do a prenatal origin story for Robin down the line. There are no MRIs involved. There’s an episode coming up where we learn how Robin’s parents got together.”
They go on to reveal that in Episode 17, two recurring characters will be introduced that include "Dr. Dulmacher (aka another Dollmaker), this time conceived as a mad European scientist, and Reggie Payne, an old army buddy of Alfred’s who has gone a bit to seed."
I don't suspect that we'll see Robin ever make an appearance in the series. After all, if the series runs its entire course it will only lead up to the point where Bruce Wayne becomes Batman. Using his parents is a fun way to build the mythology of the character though.
