I don't know if this has changed or if it's variant text with an unknown trigger. I didn't do the Dr. Myers quest in-run, which might have something to do with it. But I met Andrea on the beach and found out about Dr. Myers, and found his office. I agreed to help Andrea and now when I do he says this as intro text:
Have you been able to help Andrea?
I hope she hasn't gotten herself injured again. Last time, she brewed up some crazy ointment out of the local wildlife…
So, yeah, if you're near the Slags stop by the shore and see if you can find her.
I sure hope I can still get a sampling kit somehow.
