Currently I'm around the part after I kill Dwayne or Playbox X. I was just about to start the mission "Harbouring a Grudge" when I realised I didn't understand the storyline fully as I have been away for a few days and forgot some things. Who is Packie McReary, who is Officer McReary and who is Francis? How did Niko know where to go to start the mission "Harbouring a Grudge"?

And sometimes there is this cross icon on the radar, when I went there, a cut scene showed some guy calling Niko comrade and handing out a couple of dollars. Why and what is this?

The guy that handed Niko a few dollars is a random character, one of many you can meet. His name is Brian. Francis and Packie are brothers. Fracnics is Officer McReary, a corrupt cop. They also have a brother named Derrick.

OK Thanks.
