Crushes are a recurring theme, but there is no sexual dialogue.

There are very few scenes which include hand-to-hand combat.

Intense scenes are very frequent, as main characters are constantly harassed, chased and monitored by the evil Greencorp company. Recurring characters put their lives in danger in many situations, which are sustained and realistic, although they mostly end up fine.

There are frequent situations where main characters resort to activities that may be considered criminal or dangerous (e.g. breaking one's locker, stealing, chemical manipulation), for their plans to succeed.
