This episode seems to focus more on Ashley.
In this episode, Ashley gets a visit by her grandmother. In the beginning of the episode, the grandmother tries to help Ashley find a date. Ashley passes off Carlos as her boyfriend, even though he was just a friend to her. This particular grandmother seems to interfere with Ashley too much. In fact, Ashley was interfered with so much that she was even delayed in helping the other Rangers fight a monster at least twice. However, Ashley's grandmother was even brave. Unlike other civilians of Angel Grove, when Ashley disappeared from her grandmother's view for the second time, grandma "borrowed" a police car, & in the process of searching for Ashley, she hit the monster several times, thus saving the Power Rangers from getting eaten. From that point on, it seems that Ashley dominates the rest of this episode. She takes the front seat of the Astro Delta Megazord, & basically seems to take care of the monster single-handedly.
Out of a scale of 5 points, I give this ep a 4. By the way, it seems that now the Blue Space Ranger (T.J.) is the only Ranger who has not been given any special attention in any PRiS ep to date. Therefore, we should expect to see an episode which focuses on the Blue Space Ranger pretty soon.
