I was sure till recently that the MIB just gave Jack a flesh wound. The Source's electromagnetism killed him.

But Atarada and I have been talking back and forth here and here about it. A lot of evidence suggests the Heart did little more but teleport him, and the knife wound killed him.

What should Lostpedia say killed him?
