Darius met and fell in love with Vanessa Ambres. The couple was engaged to be married at some point before May 2016. Unfortunately when Zoom invaded Central City with an army of meta-humans, Darius was killed by some of his soldiers.
After Darius' murder, Vanessa began harboring a grudge against all meta-humans, which eventually lead to her working with Orlin Dwyer/Cicada. Vanessa would be in pain at the mere mention of her fiancé's name, as she still deeply loved him.
