Gabby is memorable for her boisterous and eccentric personality, her relationship with Ellie, her alliance/rivalry with Grett, and for helping Tom uncover the mystery of the animals being killed on the island. Gabby loves nature so if anyone hurts something that has to do with nature she'll threaten them brutally. Gabby has a clone of herself that only she can see, which constantly manipulates her and is cunning and devious, implying that she suffers from a mental disorder.
