Determining the nature of spectral variability in gravitationally-lensed BAL (broad absorption line) quasars is important for time-delay and microlensing studies because the delay-times can be comparable with the time scales of intrinsic QSO ionization changes. Far-UV spectra of the candidate lens UM 425 = Q1120+019A and PG1115+080A (Triple Quasar) revealed the presence of strong O VI λ1033 emission. In both cases, absorption in the blue-wing of the O VI line profile indicated characteristic BAL outflow.
