Leon S. Kennedy looked at the man that was standing next to him, and he said some few woeds to him:
My name is Leon S. Kennedy, the Special Agent that is in charge of the people of the northern area of Raccoon City.
The other man seemed to have some combat skills looking at his body, but inteligence was important too, and he didn't seemed to be very smart (atleast for the face). When he was about to say something to Billy, he suddenly turned to the place where the other man had entered, to see a new and familiar figure standing right there, saving the other man from entering to a dangerous place. He recognized the face indmideatly: That man was Chris Redfield, an Ex-S.T.A.R.S. and old friend of him. From what he remembered (*and for what I have readed*) Leon met Chris before the events on Rockfort Island, advertising that Claire, his sister, was in trouble. Nemesis was a big problem, so he turned to Billy and said:
Hey dude, we may need a bit of help with this Nemesis guy, wanna help us?
