General Hospital spoilers suggest that there could be a paternity plot twist where Desmond Robinson Ashford (Yirah Aviah Lafond) is concerned. This might also affect Desmond’s paternity. If Curtis and Isaiah are brothers, there’s a good chance that Curtis would be a false positive for Desmond’s paternity tests. So, could there be a plot twist coming soon that Isaiah is actually the baby’s father? Could GH be setting fans up for a plot twist in Desmond’s paternity story?
