I've just finished A Dance With Dragons and realized that the Red Comet which appeared in the early books had made no appearances lately.
I've been reading the series before going to sleep so I wasn't always at my most alert and may have missed it but I don't remember anyone commenting about the comet disappearing. Since it seemed to be such a big deal for many people I would expect the plot to reflect when it stopped appearing (or if it didn't stop why is nobody noting it as they did in the past?).
Did I miss something?
