Arrow Season 06 Will Have Father/Son Dynamic
In Arrow Season 02, we found out that Oliver had caused a girl to get pregnant. His mother, Moira, had paid off the girl to leave Starling City and not tell Oliver and tell him that she lost the baby. In Arrow Season 04, Oliver found out that his child was indeed still alive, and thus made a deal to try and see him when he could. In Arrow Season 05, his son, William, was kidnapped by Adrian Chase, and used as bait to lure Oliver to Lian Yu for the season finale.
