I was going through HL2:Ep2. Alyx was just resuscitated, and we
emerged from the mine. I got a car. She sat into the passanger seat of
it, and told me to drive through the tunnel. I left her and walked
through the tunnel. The game loaded a new map. I found myself near the
exit to the tunnel. And guess what ? Beside me, there was Alyx in the
car. She obviously drove it to keep close to me. And here she was in a
passenger seat ! And she wanted me drive her further !

I did not get into the car. I left her. I explored the area on feet. I
crossed the river, and went to the radio station nearby. It was maybe
a kilometer or two from the tunnel. I jumped into the room which had a
passage to underground. And guess what ? Alyx was outside of the
building, giving me suggestions. She drove to here ! What was this
bitch doing here ? I left her !

And the rest is the history. I went underground, connected the cables,
got upstairs, and was attacked by the Hunters. We fought. And then she
wanted me to get her outside of the gates. Why cannot I be left
alone ?
