Very hopeful that it's an extended arc leading up to Cass resuming her rightful place -- Steph still dresses (and thinks) in purple. The handoff was definitely handled abruptly and badly (and Tim's going through the same kind of erratic lashing out, ugh). I'll be bothered if Cass doesn't bounce back in black, but if Steph is erstwhile eggplant eternally, I'll be enraged. Robin for a while, ok, Batgirl for a while, ok, but Steph = Spoiler.
