Good idea, can't have EVERYONE in the same place, that would get... complicated. Could create Morinth to be a teenager with hormones who acts out merely as a phase of adolescence... or she could be written as a complete sociopath with a desire for manipulating others for her own pleasure. She'll probably try that on Shepard, both maybe... Jessica would be nice and turn her down but insure the idea of her not being interested is clear. Elliot... well I could see him saying a simple, blunt "No"
