So, I found the pulse gun. After a nightmare in vault 34 was it? Anyhow, after talking to the brotherhood elder we got jumped out front the bunker. We killed the guys who attacked us. Then after some talking and she says she can still roll with me, I jump to the strip. She never showed up

I go back and she is still standing outfront the bunker. I cant get her to move on her own at all. What do I do?
EDIT: The quest is called "I could make you care"
