Actually... *everyone groans because they know 
Yuki is about to be a nerd and correct 
someone*... the glasses scene is from when she 
runs into Mo-chan, Inaho, Honoo and Yuki on the 
ship for the first time in hundreds of years.

Yes, it's a very pretty sequence, but as a 
collector from the Mosquito OVA I'm not gonna 
lie... it's not the best animated OVA in the 
world. ^^;; That particular scene probably got 
more attention than most of the series, which is 
why so many cels from it spring up.

It's a 'beaut though! :)
