I'm wondering if this guy is pretending to be this doctor, setting your friend up this whole time, getting her all excited to finally meet him, then when the day comes, and the Dr. doesn't show up your friend will be sad and upset--Out of town and away from home. Then this looney who has been baiting her this whole time (pretending to be this dr)will introduce himself non-chalant like and be the "shoulder for her to cry on" when she's so vulnerable. He sure sounds like a psycho to me. And noone would ever know about him...all anyone knows is she was going to meet the "dr".
I hope over time, (what little there is before this encounter) that she wakes up.
