I totally agree on every count here. When we got the teaser/summary for "Corazon" and everyone was running around like headless chickens, I had a "holy shit ZACK" moment, because my mind went like this:

~ Both characters had significant changes in hairstyle
~ Both were hugely beloved by me
~ I never saw it coming (despite all of the little "welp, it's genetic" moments for Reid) in either case.

I had to reassure myself repeatedly that there was no way CBS was dumb enough to start in on a schizophrenic!Reid storyline.
