It almost feels like it isn’t a spoiler at this point, but confirmation is confirmation is confirmation.
Early in the issue Rose and Red reveal more of their shared history, including that Rose is a telepath who knows of Red’s true abilities, which are being kept hidden from N.O.W.H.E.R.E.
Later on Superboy returns after a day in the real world to ask Red some questions.
Which would be easier if she didn’t go from bookish little girl to giant amazon like red head in a green and purple bikini.
In other words, Caitlin Fairchild.
