A little more on Lehir (Leticia's older half brother): He was eaten by Darkness as a child, so for many years, his soul was in such terrible pain (he couldn’t speak or communicate), and eventually his soul shattered/died. Josephina (who actually loves her son) was crying out to him in pain, due to the curse placed by Sigmund (Leticia’s original curse), but Lehir (aka Darkness) was pissed off at her for losing her wings so he was just screaming at her.
