I do understand that she likes to tease Ryoko and 
that she has a pretty warped sense of humor, but 
what happened seems a bit too much. At the 
beginning of the sequence, it was pretty amusing, 
but toward the end, it got pretty uncomfortable. 
Besides, *spoilers* for those who haven't seen 
the Tenchi OVAs, after the merging of Zero and 
Ryoko, I didn't think that Ryoko needed much 
urging to let her feelings show.
