Sagax's Virtue was easy enough to decide: Charity. Had to think about his Sin for a few minutes though. Decided that his hero complex and propensity to throw himself into dangerous situations would leave him with the Sin of Pride.

Piper's Virtue would most likely be Diligence. That woman is so headstrong and persistent she could probably headbutt a hole straight through a Kamal frigate. Her Sin, and this was probably painfully obvious to...literally everyone, is Wrath. Hm, Diligence AND Wrath. In the same person. Something something chase you to the ends of the earth.
