In Die Hard 2 Holly and Dick have a heated exchange in the plane and she says something like "Listen, buster. You endangered my children and you didn't do it for anything as noble as the people ..."
In Die Hard his news report causes her to give away who she is to a very astute Hans but I am not aware of them actually being in danger. I always assumed it was a retcon to make Dick more villainous and Holly more sympathetic to the audience.
However, my brother in law thought that there was a chance that Hans could order someone to come after the children.
Have I missed a reference in the film that makes this likely?
