Crank ending explained (spoilers)

[kenneth]

Chev makes a deal with Verona, the cure for his brothers necklace. Verona agrees and Chev meets him at his place. Verona doesnt give him the antidote, but Chev had the Chinese mafia, led by the man he didn't kill, come in and save him from being shot. Verona tries to escape via helicopter. Chev chases after him and hangs on to the chopper. They fight some and Chev is pushed out of the chopper, pulling Verona with him. Chev kills him midfall. During the remaining minute or so of falling, Chev calls his girlfriend and basically says hes sorry. He falls onto a cab, bounces up and lands right in front of the camera, seemingly dead (We are not meant to know as he blinks, so the fall could infact have been the cure)
