We have monitored both NGC5548 and NGC3227 roughly weekly, with 30ksec exposures, throughout a 2 month Suzaku observing window. These intensive monitoring campaigns were designed to find the location of the Warm Absorber, but have proved of much greater value. We find that: 1. The WA in NGC5548 is mostly at >5000 r_g = and so has a large kinetic power - and has 2nd component at <3pc 2. The narrow Fe-K line in NGC5548 responds weakly to continuum changes, putting it at 20-40 light-days, inside the hot dust sublimation radius, but outside the H-beta emitting broad line region (BLR); 3. NGC3227 shows rapid, strong, changes in N_H, implying rapidly moving dense clouds at BLR distances, quite unlike previous behavior of this object; 4. contemporaneous Swift UVOT observations of NGC3227 show no change in reddening, limiting the covering factor or requiring a dust-free X-ray absorber. Other results will be presented.
