TR7
Trust in Sean Marks
my only question is why would lucas black from tokyo drift be involved with a revenge plot for paul walker?
I assume he's involved with a revenge plot cuz han got murked at the end of F&F 6 and han looked out for him in tokyo drift.
That's why he's there, because of the revenge for Han's death and tying together him and Dom meeting in TD. 7 would have shown stuff after they raced with him explaining who killed Han and why, and he and Bow Wow's character would join up.
As long as they keep that part in there then the TD characters can stay in the movie. I don't see them dropping that, and like others are saying I think they write Brian off screen to go into hiding to protect his family, killing him cuts too close to home.
