At the mall, what do Dimitri and Rose talk about?

Rose mentions that she wants a silver stake. Dimitri asks her if she is really ready to fight Strigoi, even if the Strigoi ended up being someone that Rose knew before. Dimitri asks Rose what she would want if she were turned into a Strigoi. Rose answers that she would want someone to kill her, which reminds Victor of Ms. Karp and her guardian lover.
