Forum:How can i save both morinth and samara for ME3?

I wonder what's gonna happen in ME3 if I simply let Morinth get away at the bar scene... but i want to keep samara too, so the question is: is samara gonna die if she is disoyal at the final mission and I won't use her for anything(biotic field, sewer.... blabla)? Beacuse i really want to what will happen in ME3 if both of them are alive... :D anybody with help how to keep alive Samara? Thanks.
