Once Wendy had the baby, Oliver demanded she stay home and take care of his child. What she wanted or didn’t meant nothing to him.
Although he considered her love for him a leash, having a child was a chain.
Further, knowing she wanted American citizenship and he was the only one to give it to her, cemented her in place.
Wendy belonged to him. Wendy was dependent on him! This was the joy. The joy of actually having a person ‘beneath him’.
All the years in which he suffered in his grandparent’s home, all the years he had been treated as a wart by his mother, could now be excreted. Oliver had all the power.
