Just as Tian Xingjian had guessed, Bonnie indeed had acrophobia; this was her most hidden weakness, even Reinhardt didn't know. Unexpectedly, in her panic, it was exposed in front of the conniving Fatty.
As a Mecha Warrior, leaping and maneuvering on cliffs was unavoidable. Fortunately, acrophobia sufferers only wouldn't have an episode if they didn't directly face dizzying heights. Bonnie's modified [Mika] with its fully enclosed simulated control system completely helped her overcome the fear brought by facing heights directly. This is why she persisted in using a sixth-generation private mecha even after [Vajra] was produced.
In this unfamiliar mecha, flying and leaping from danger to survival was an experience Bonnie had never felt before. Unexpectedly, at the last moment, she jumped off the cliff with her eyes wide open.
