Poor Misty.  It's bad enough she has to dodge Jessie trying to steal her Poke-Balls.  But she also has to put up with her older sisters hazing her?  No wonder she's constantly on the road.

I remember doing this right after I saw the "Misty The Mermaid" episode because I thought Misty just looked so elegant as a mermaid.  Tomboys have a feminine side.  They're just loathe to show it.
