I think they wont have a comeback in November despite their initial projection- eric is back and having two comebacks without him also ruins the discography for future performances? Maybe it's better they don't have a nov comeback considering that they already were so pressed for time when it came to Whisper. The reason why they didn't have a comeback showcase for Whisper was because it wasn't feasible- they hadn't learned all the parts of the choreo for a live stage, they only knew enough for the chorus for the MV.
