You can't go home again.
Though Diana lived full-time in Man's World and had for some years it was not uncommon for her to be summoned home. There were various reasons why she might find her presence requested--a festival, a holiday, the general health and welfare check her mother was insistent upon. This time Diana was being summoned to celebrate a birth and she was looking forward to this trip home, though the idea of leaving her duties...and Bruce...was unpleasant. Still, she took care of loose ends and headed home, leaving Diana Prince behind by the time she arrived on home shores.

It was good to be back. Diana went to find her mother.
