The official trailer for Jack Reacher explicitly laid out many, many traits about our titular hero, among them: Jack Reacher is a ghost! Jack Reacher wants the truth! Jack Reacher is not a hero! Jack Reacher has no limits! Jack Reacher has nothing to lose! And so on.
This new TV spot covers one key Reacher facet that trailer missed: Jack Reacher will go into an auto-parts store and demand to know if "Sandy" works there, then threaten violence if the employees won't tell him, because beyond being "a ghost," Jack Reacher is also an overly-aggressive ex-boyfriend archetype. He has nothing to lose! Not since he lost Sandy.
