Changing-look Active Galactic Nuclei (CLAGN) have dramatically altered our understanding of the astrophysical processes governing supermassive black hole accretion. Gregory Walsh will discuss VLBI monitoring of two CLAGNs, Mrk 590 and Mrk 1018, and place these in context of theories invoking dynamic magnetic fields down to the SMBH scale itself.
