Mordin launched into one of his characteristically meandering speeches, occasionally breaking concentration and singing it along to the lullaby in his head before gathering himself.

"Cross-species interaction important. Reduces fear, misunderstanding, prejudice. Avoids war. Asari, turian, salarian, volus, elcor--all relatively peaceful. Shared interests in galactic peace. Hoping to learn about humans. Not repeat Rachni Wars. Bloody introduction to a species. Immersing self into human culture best way to promote amity. Selfishly, fascinated by prospect of learning new culture. Xenoscience is passion."

Mordin stopped his rambling to take a deep breath. "Formally learning meditation, etiquette, and philosophy. Self, interpersonality, and ideology through human eyes. Informally learning that everyone has a more impressive singing voice than myself."
