I wanted her to be the Rival. Since she isn't going to be the Rival I don't care what they do with her.What's wrong with her being a traveling companion with a goal?
Now that she's actually with the group she's doing about what I expected her to do. She's supportive as Ash. She's occasionally helpful. She's occasionally a damsel in distress. She has little quirks that show up in the plot from time to time. She'll probably catch some cute Pokemon and do some cute things somewhere down the road.
That's what I expect. If we get more than that I'll be surprised.
