After their not-so-long coffee run, Scarlet and Erica returned to the city Library and began their search about dragons, they had come down with a theory that stated that if dragons could conceal their presence to hide within humans, that would imply that staying human form would become very uncomfortable at some point, so every moment in awhile they had to return to their original forms to keep that balance possible.
Only one of them had a fair amount of knowledge when it came to having an idea on dragons, as for Erica, she only knew about the dragons in books and movies, anything that wasn't fiction related was pretty much nothing important to her.
