Considering how close Aisha and Rocky are, it's no stretch of the imagination that they could have been romantically involved at some point. Maybe they dated first, and then became friends? Or perhaps one held an unrequited amour for the other? Maybe there was something behind those amused looks the two often shared? After all, Aisha and Rocky both strike me as being the fun-loving members of the Ninja Rangers, and their long friendship could very well form the foundation of stronger feelings.
