>>43145194Ash never friendzoned her, in fact he gets jealous whenever other guy flirt with Misty. Also Misty never really shown any thirst for Ash, she mostly cared about Ash's well being. Since Ash intentionally provokes her implies his feeling for her since kids around that age often tease the girl they likes.
Out of all the girl, Misty and Giselle are the only two girls that Ash has shown signs of liking.
