Fern starts out determined to win the race. However, she turns friendly after Izzy comes to her aid when she hurts herself. From this point forward, Fern and Izzy slowly cement a relationship. Between the pair, Fern is the sensitive and compassionate foil to Izzy's tomboyish and competitive nature. Yet the two come to respect and admire one another in spite of each other's quirks, even as outside influences often keep them apart for extended periods of time. But when Fern finds herself in a thorny situation, she knows she can count on Izzy and her friends to help her deal with it.

Though Fern falls all too often into being the one in need of rescue early on (see above), in later episodes she is shown to be quite brave as she went to go save Solon from the Scuttleworms. She also has a knack for finding solutions her friends cannot at any given moment. Most importantly, Fern is a fast learner, as evidenced by that she adapted to her nascent Ranger powers in a very short amount of time to be able to take the fight to the villains; and although Izzy remains overprotective of her at times, Fern can hold her own in battle.
