P and the extremists

P (someone who I have mixed feelings about - an intellectual with unresolved emotional issues) was in the house. To begin with we were alone together, and it seemed that we were communicating well and building trust. There was a softening in his usually serious attitude.

Later there were other shadowy figures around who were not clearly visible, but seemed to be potentially violent extremists. There was a growing sense of danger of some kind of violent outburst or event. I was unsure what connection P and these figures had. 

At one point I was approaching the house with a female friend, cautiously, warning her of the situation. The sense of there being potential danger had grown.
