The event-centered model of the imperial social formation thus works to restore the unpredictability of the twists and turns that make up the process of historical change. The recognition of unexpected moments of rupture in this model draws attention to what Duncan J. Watts calls a nonlinear view of historical causality: that is, an understanding of causality that 'renders the relationship between initial cause and ultimate effect deeply ambiguous.'
Mrinalini Sinha, Specters of Mother India, p. 18
Displacement-- initial cause not producing "ultimate" effect-- what you think will happen does not happen-- in the film Illegal Assia died but Tania escaped-- cause similar but racial/ethnic difference but also-- chance-- singular moments allowing for rupture-- who escapes and who doesn't-- movie moments-- but also the unpredictability of possibility.
Displacement as a nonlinear continuum, a vast space between what is no longer possible & what is happening.
