Question: Just to clear something up. Dietrich and Sasha are meant to be brother and sister, so what does the kiss mean? (In Dietrich's loft apartment, during the shootout, just after Dietrich is shot in the neck). Are they actually brother and sister, or is it a sham? Or does the "You look like you just f***ed your mother" joke to Castor Troy have hidden meaning (i.e incest?) Or is it just a last goodbye between siblings?
