Hans’ death Mystery.
Tokyo Drift – he was hit by an unknown car, stucked in the car explode and died. No one come out from that unknown car before Hand FD explode
Shaw Saga – it’s appear it’s Shaw hit Hans. Come out from the car and witness the explosion
F9 – surprise! Hans’ is back, unscratched.
Conclusion: it’s either Fast franchise decide to make it into like Bollywood style or that is Hans’ long lost twin brother just like Lockon Stratos twins. I mean, there’s no way he could escape from that explosion. Even Sherlock Holmes need Reichenberg Fall to fake death, Akai Shuichi also need times preparation to get a dead body to replace himself.
