Why did Dualscar kill Dolorosa? Was he jealous of their relationship despite him being the one who broke up with Mindfang? Was he mad that a highblood like Mindfang slept with a midblood? Or did he recognize her from the Signless' execution?
He was upset that Mindfang stole her from his ship since the Dolorosa was his slave. He was also jealous that Mindfang was sleeping with lowbloods. Dualscar is also a mean guy.
