I can't really describe it anymore, but at the beginning someome was coming to attack Mac and the chinese woman (who is part of an anarchist group in China). Someone jumps in to help (Sam). They go inside, Sam talks about his mom and how she was killed by a group 20 years ago....Mac can finish the story for him! Sam opens this locket type deal, that has a pic of his mom and MAC!!!! And then he says....that means you're my dad, or something like that.
They go back to the Phoenix Foundation (is Pete blind or something?). THey look for clues about this group and wouldn't you know Sam is pretty gosh darn smart as well....just like his daddy! He keeps saying stuff about living alone, being strong, intelligence and how his mom said that he got it from his dad.
They have father-son and son-father talks (pretty interesting). Built a flying contraption, save the Chinese woman and Sam stops her from shooting the lead hit man (just like his dad told him to do in a talk...awww he listened!).
Mac "resigns" and the two drive off on the motorcycles.
