All Neat in Black Stockings

Ginger decides to marry Jill despite knowing the child is Dwyer's because he feels a sense of responsibility toward her. The film presents this as a practical outcome rather than a romantic one, Ginger had been pursuing Jill genuinely, and her pregnancy creates an obligation he feels he must fulfill. His remark that the baby looks like Dwyer shows he awareness of the situation, yet he proceeds with the marriage anyway, reflecting his passive, easygoing nature.

Ginger kicks everyone out because the house he borrowed from the hospital patient has been trashed. He feels responsible for the property since the patient trusted him to care for it and his pets. When he arrives to find the place destroyed, he takes immediate action to protect what remains, showing his sense of duty despite his generally laid-back attitude.

Earlier, Ginger had been entrusted with caring for the patient's pets and home, establishing his stake in the property.

Ginger refrains from having sex with Jill because his feelings for her are different from his previous relationships. Unlike his casual encounters with other women, Jill represents something more meaningful to him, he even buys her a plush penguin and forms a genuine connection with her mother. This restraint signals a rare moment of sincerity in Ginger's typically carefree approach to romance.

Dwyer notices a change in Ginger's behavior, marking this as unusual for him.

Dwyer sees nothing wrong with being with Jill because he and Ginger have an established arrangement where they regularly swap women. Since they have always slept with each other's partners, Dwyer assumes their mutual arrangement still applies. He doesn't consider that Ginger's feelings for Jill might be different this time.

The film establishes early on that Ginger and Dwyer swap dates and women casually.

Ginger's pushy brother-in-law leaves for Mexico with Jocasta, Issur's girlfriend. This departure reduces the crowding in Ginger's already cramped bedsit and removes one source of tension from the household. The situation simply resolves itself as they choose to leave together.

A hospital patient asks Ginger to look after his birds, rabbits, white rats, and aquaria while staying in the hospital. Ginger accepts, partly because the borrowed home is far nicer than his run-down bedsit, but also because he's someone who takes on responsibilities when asked, even if they're not his obligation.

Ginger makes a deposit on a rental property intending to live there with Jill, but Jill chooses to continue living with her mother instead. This decision reflects her preference for staying in her familiar environment and keeping her support system close, even after having the baby. It also suggests a pragmatic approach to her relationship with Ginger.

The ending shows Ginger returning to his window-cleaning routine and immediately flirting with a young waitress at a café. This suggests that despite marrying Jill and becoming a father, Ginger hasn't fundamentally changed. His character remains someone who constantly seeks new romantic encounters, and the marriage hasn't tamed his wandering eye. The open-ended nature implies his pattern will continue.

The film establishes early on that Ginger has 'an eye for the girls' and struggles with commitment.

Jill loses her virginity to Dwyer on the same night Ginger discovers them together in bed. Dwyer saw no issue with this because of their mutual arrangement to swap partners. The encounter happens while Ginger is busy kicking party guests out of the borrowed house, creating a dramatic irony where his focus on the property leads to his romantic betrayal.

Ginger's earlier restraint with Jill contrasted with Dwyer's usual behavior sets up this betrayal.

Ginger switches his planned date with Carole for Dwyer, continuing the casual swap arrangement the two friends have. This illustrates their loose, competitive dynamic where women are shared freely. The swap happens late at night as Ginger contemplates the arrangement, showing his willingness to move between partners without strong attachment.
