Selling Miria to Metzger will not mark you as slaver though.
Miria is so vulnerable and you cant tell her to wait somewhere before u know u go into combat that in order to save her life I sold her to Mtzger once.. figure anice piece like her will be put ina brothel.. (and not jet experimented...
Its an incredible game... I must admit I struggled leveling up and built my character for success in vanilla FO2... but NV is different... And incredibly bug free. Now on my 2nd playthrough I found a bug but I will probably just playthrough again.
