Really, though... I gotta hand it to Sasha. Telling Selene they could have a threesome right off the bat? Gotta respect her for willing to go full-on debauchery mode even though it'd be everyone's first time.
The sob story is just that - a story. But with the lord's daughter herself confirming it, seemingly without any duress caused by the demons, it makes sense. Keep your sword out, but don't go swinging it just because you want to.
