Abstract
For a scalar CFT with a monodromy defect, a `subtracted Green function' is derived in terms of an Appell function. A conjectured relation of Gimenez-Grau and Liendo is thereby proved and extended and shown to hold for generalised free fields. A possible means of determining the bulk block expansion is outlined. Finite coincidence limits are expressed as combinations of Beta functions.
