Passing gives considerable attention to the marriage dynamics, and the quest for satisfaction, existing within the Redfield and Bellew households. For Irene, Clare, and many of their peers--Gertrude, Hugh, and even minor characters such as Felise--marriage appears to offer a source of security and partnership. Yet as Larsen's narrative progresses, the seeming stability that marriage initially offers is exposed as deeply problematic. Irene's marriage is strained by the possibility of an affair between Clare and Brian--and by Brian's lingering discontent--while the marriage between Clare and John Bellew is driven to the point of crisis by a very different factor: Clare's hidden ethnic identity.
