We reconsider cosmological perturbation theory for multi-component scalars,
enforcing covariance in field-space, and ensuring that phyical observations are
independent of field re-definitions. We use the formalism to clarify some
issues in the literature, and use pseudo-supersymmetry to derive exact
expressions for terms of interest.
