That's not where Noriko tells Miaka she lost the 
earring though. (that is like episode 3 or 4, and 
tamahome is wearing a sky blue shirt).
In ep. 5, Miaka is sick, and Nuriko tells her 
that the pool has "magical" healing properties, 
so Miaka goes to bathe there.  (this way Nuriko 
knows she'll be naked when she sends Tamahome 
after Miaka, hehe....)
Wow, I fogot how much Nuriko lied at the 
beginning of the series.  ^_^

Your psycho FY junkie, hard at work.  :)
