Dominick secretly changes his college roommate

Dominick’s secret change of college roommate makes a private decision about university housing into a rupture in the twin brothers’ familiar arrangement. After years of living closely with Thomas and feeling responsible for his difficulties, Dominick chooses to room with Leo instead. The change is practical, but its disclosure exposes how much Thomas has relied on their closeness—and how urgently Dominick wants a life not organized around that responsibility.

Background and Decision

The decision comes after Ray agrees to help pay the twins’ tuition. At supper, he gives Ma a two-thousand-dollar check for the bills due that week, and Thomas promises to keep up with assignments, go to bed earlier, take walks when nervous, and study at the library with Dominick. As Thomas lays out his plans to do better, Dominick silently resolves not to supervise him: he will not walk Thomas to the library, hold his hand, or cover for another outburst against their typewriter. The contrast is central to the scene. Thomas imagines improvement through continued closeness with his brother; Dominick wants Thomas to manage without him.

Dominick has already acted on that wish. Three weeks earlier, he and Leo secretly visited the university housing office and requested to room together at South Campus. The change has been approved, so the conversation at home is not a proposal or a negotiation. It is the announcement of a decision Thomas was not allowed to help make. Dominick also plans to travel to Boston College on weekends to spend time with Dessa, another life he wants to protect from the demands of the brothers’ shared routine.

A car is part of that plan. Dominick cannot ride his bicycle up the Massachusetts Turnpike, while hitchhiking has proved unreliable and sometimes frightening. His previous rides have included a driver who claimed to have explosives in the trunk and another whose wife, high on acid, thought Dominick’s head was on fire. These experiences make transportation a concrete obstacle to seeing Dessa, while the roommate change addresses a different obstacle: Dominick’s sense that he cannot pursue a separate life while continuing to live with Thomas.

The Disclosure at Home

Thomas learns that his assigned roommate for the 1969–70 school year is Randall Deitz, a transfer student from Waterbury. He receives the university letter before Dominick comes home and waves it at him, complaining that the arrangement must be a mistake. Dominick confirms that there is no mistake. When Thomas and Ma wait for him to explain, he tells Ma, rather than looking at Thomas, that he will be rooming with Leo.

The avoidance makes the announcement more painful. Ma’s face pales, and fear appears in her eyes; she tells Dominick to address his brother instead of speaking around him. Thomas asks whether Dominick and Leo went behind his back to change the arrangement. Dominick acknowledges that they did, but initially minimizes the decision and says he has been busy. His explanation gives way to a more direct appeal: Thomas will meet new friends, Randall might be a good roommate, and the twins are so close that they get on each other’s nerves.

Thomas’s reaction is conveyed through his body as much as through his words. He flops back into a kitchen chair, crosses his arms, and cranes his neck away from Dominick. He says nothing for a minute or more. His earlier complaint about the roommate letter thus becomes something larger: the official assignment confirms that his brother has arranged a future in which Thomas is no longer the default companion.

Separation and Its Cost

The change is not a rejection of Thomas’s plans to improve, but it does reject Dominick’s former role as their guarantee. Thomas had included studying with Dominick in his promises to Ray; Dominick privately decides that Thomas must succeed or fail without his help. Their opposed understandings of support give the housing decision its force: what Thomas may experience as abandonment, Dominick presents as a chance to meet new people and as a necessary limit on their closeness.

The scene does not resolve that conflict. Dominick has already secured the room change, and Thomas’s silence leaves his response hanging rather than turning the conversation into reconciliation. At the same time, the new arrangement opens space for Dominick’s weekends with Dessa and a life beyond the twin partnership. The episode marks a concrete step toward separation, while showing that choosing independence does not make its consequences painless for either brother.
