In "Jane Doe #38B" Sharon gives Jack a choice between adopting Rusty with her or divorce. The whole scene is pretty much an Awesome Moment for Sharon, but in particular her response to Jack threatening to take half her savings and half her pension in a divorce:
Sharon: So you're ready to pay me all of the back child support you owe me for the family you deserted?
Jack: We were never divorced! Why do you think I owe you?
Sharon: Would you like to experience firsthand what the court thinks of child abandonment? Go for it.
