In Chapter 7, what does Dimitri tell Rose about Strigoi?

Dimitri asks Rose what she would do if a Strigoi attacked Lissa. Rose says that she would kill the Strigoi with a silver stake, but Dimitri reminds Rose that she has not been trained on a silver stake, and does not have one. Dimitri points out that she is too short to behead a Strigoi, and has no way to set one on fire, and therefore could not really hope to defeat one at this point. Dimitri tells Rose that, at her current level of training and skill, her best option would be to run from a Strigoi and hope she gets away.
