Skulduggery’s child died at the age of four
Tanith and Stephanie are flicking a piece of Hollow Man skin back and forth, and Skulduggery snaps at them. as much as he loved his child he remembers all the trials he went through raising them. When Tanith and Stephanie were acting childish, this only brought back memories. he’s not mad at Tanith or Stephanie, he just knows it’s not an appropriate time to be dwelling on his child’s passing.
