blame it on the hesitancy

Lymph nodes run amok as they attempt to control the viral plague known only to a few as the Blue Paint Enigma (BPE). BPE started out as a test chicken noodle soup recipe but when one extra malignant ingredient was added, a reaction took place creating the foundation for BPE to spawn. This was all kept hush-hush from the soup manufacturing company as tracing this back to them would have severely dire consequences.

Once a subject catches BPE their skin turns the most subtle shade of blue and they begin to have an intonation in their voice that is just barely perceptible. If you are aware of BPE and can perceive this change in intonation, you'll hear the cluck-cluck of chickens.

There is currently no known cure for BPE but one is in development. Researchers are concerned, however, that BPE can only be cured by GTET (Green tinged epidermal tissue) which cures the BPE vocal effect, but alters one's entire skin surface to be slightly green.
