7. Hypothesis 1: Microlensing
Integral field spectroscopy from [Wisotski et al. 2004] shows that A/B continuua are identical while CIV difference persist
Microlensing unlikely to amplify part of the BELR but not the continuum region
CIV blue wing enhancement disappears and reappears
Strong profile differences persist in CIII] and MgII [Richards et al. 2004], which originate from larger regions.

8. Hypothesis 2:Intrinsic Variability
The asymmetry (rA-rB)/(rA+rB) of the A and B images wrt the lens means the maximum delay between them is <30d [Oguri et al. 2004]
B never showed a bluewing bump, although
it persisted in A for >>1 month. [Richards et al. 2004]

13. Geometry θ From absorber distance; image splitting
LAMAS and variability in SDSSJ provide complementary constraints on absorber size
From rotation speed; variability timescale
(a<300AU)
θ From absorber distance; image splitting
 No match for
~RBELR
(~100 lt-d or 1017cm),
but OK within recent BALR distance estimates of 5 – 700pc (deKool et al 2001, Everett et al. 2002)  30<a<3000 AU

16. LAMAS
The A image of SDSS J shows variable spectral differences not easily explained by microlensing or variability+time delay.
SDSS J1004 and other lenses may illustrate that small angle changes to the nuclear region can strongly affect spectral details.
The spectral differences mimic differential absorption from a high column, highly ionized wind.

17. Further Implications Quasars have high column, highly ionized winds.
All quasar spectra may be self-absorbed by their smoothly outflowing winds.
In a large sample of lenses, spectral difference should correlate with θ and be independent of proximity to a bright galaxy of high microlensing optical depth.
X-ray measurements during a similar UV blue emission line asymmetry event should show lower absorption in that component.
