Elliptical BLR geometries cause the virial factor f to vary by over an order of magnitude and induce ~0.18 dex scatter in the R-L relation, challenging attributions of RM uncertainties to non-virial motions or radiation pressure.

HE 1237-2252 exhibits a changing-look event driven by intrinsic accretion-rate variations, revealing a two-component broad-line region consisting of virialized gas at ~27 light-days and disk emission at larger radii.
A statistically significant positive correlation (r ~ 0.12-0.13) exists between the absolute velocity offset of broad Hβ lines and dust reddening in quasars, consistent with a population of recoiling black holes.
Multi-epoch spectroscopy of UNAM-KIAS 613 shows transient double-peaked broad Hα emission interpreted as a one-time bipolar outflow in an isolated low-luminosity AGN with Eddington ratio ~0.03-0.04.
