Guys, this is pretty easy as long as Du paid attention to the movies. Copy and Paste the Link.
link The end of these movies, there are little clips that tie them together.
Han is killed in Tokyo Drift. When Du see him at the end of Fast and Furious, he is on the Autobahn heading to Berlin.
While he is driving the car, the girl in his lap says, "I thought Du wanted to go to Tokyo?" (In the Fast Five, we find out who the girl is.)
Han replies, "We'll get there... in time." (You also see the same clip at the end of Fast Five.)
Both of these Filme happened before Tokyo Drift.
Read the Link if Du are confused.
