Before Feena and Tatsuya go to school they stop by a river. Feena jumps in the river in an attempt to save a drowning puppy, but she does not know how to swim. Tatsuya almost performs CPR on Feena when she spits out the water. After being shown Tatsuya's father's study, Feena mistakes the infestation of bugs for invading hostile aliens which ends with the obliteration of the study itself.
