Once Samara & Morinth begin to fight they eventually come to a standstill where I was offered the option of killing one of them. Since I'm playing a total hardass I decided to kill off Samara.
Man, it was so brutal to watch her own daughter crush her! Afterward it made me pause and really reflect on the choice I just made. There was no way I was going to go back--I stuck with it.
But after Samara was killed, Morinth turns and thanks you. She then offers to replace her mothers position on the ship in honor of you saving her life. Creepily she suggests that she mimics her mothers voice and appearance (doning her mothers attire) so that no one on the ship suspects or asks questions.
Crazy!
heh !
I am playing a saint with full paragon and when I was with morinth I went on to the conversations, followed by selecting 2 paragon options couldn't select the paragon option the third time as I didn't had high enough mortality so I selected a neutral option, then samara entered the room & a conversation went on followed by Samara killing morinth....I never actaully got the choice to save Morinth lol
