On the one hand we may not have any idea why DXW wanted to continue to destination (although in this case I suspect it was more a matter that was what was offered by D and D) and it is definitely not for us to second guess those facts without knowing what they were.
Fuji, We do know the facts. You need to reread DX's post. She says that she intended to return to her point of departure; it was D&D's decision to vector her to her destination.
