notes

Temperance to Gluttony,
Chastity to Lust,
Charity turns to Greed, and
Diligence to Sloth.
Little Patience morphs Wrath,
no Kindness forms Envy,
and one with no Humility has only Pride.

Those with virtues also hold sins, and those with sins hold virtues. It is up to the person to keep them back and control how much of a side comes forward.

Or, in this case, it is the actions of ONE, and the lack of actions from another.

That is what the passengers and crew aboard The Persephone find out, the hard way.
