Knock her out

You can't risk. You must act. You rush to Ashley and strike her head with the pistol grip. She fell on the floor unconscious giving you some time to restrain her. Is is the first time you strike a woman and you don't feel good at all. You feel guilty. When you got Gwen and Lea you used just a bit of raw force, intimidation and mind games but here situation is very different. What if she suffered a serious brain injury?

You calm down somewhat after you check her pulse. It seems normal and she should be fine sometime later. This means that you must restrain her before she will awake. You find a short piece of rope and tie Ashley's hands behind her back.

Now you are safe and need to find something to do waiting till the tied beauty will come back to your senses. Making some sort of plan is always an option. Talking with Gwen and Lea is something you will need to do anyway and now may be a good time. Finally, the unconscious body looks so tasty....
