She never had a crush on him. There's a different between obsession and a crush. Hopefully, looking that up will help you identify the difference because people confusing these two words to be one and the same is disturbing.

Also again, they were always just friends.

I remember her specially saying that she likes him and that's pretty much saying crush.

Ash was more obsessed with Little Cato than in love, Even now, it could not lead to a relationship, as Little Cato is still 14 and Ash was made into an adult by Invictus. If any feelings were present, they likely faded.

I remember she has a crush.

1. Ash was turned into an adult

2. Little Cato was officially confirmed gay by Olan Rogers
