Here, we investigate these two scenarios under the scope of X-ray polarimetry, providing the first polarization predictions for an archetypal `changing look' AGN: NGC 1365. We explore the resulting polarization emerging from lamp-post emission and scattering off an accretion disc in the immediate vicinity of a supermassive black hole. The computed polarization signatures are compared to the results of an absorption-dominated model, where high column density gas partially covers the central source.
