Implications of inserting a conformal, monodromy line defect in three dimensional O(N) models are studied. We consider then the WF O(N) model, and study the two-point Green's function for bulk-local operators found from both the bulk-defect expansion and Feynman diagrams. This yields the anomalous dimensions for bulk-and defect-local primaries as well as one of the OPE coefficients as epsilon-expansions to the first loop order. As a check on our results, we study the (phi(k))(2)phi(j) operator both using the bulk-defect expansion as well as the equations of motion.
