We present CIV BLR modeling results for the multiply imaged $z=2.805$ quasarSDSS J2222+2745. Using data covering a 5.3 year baseline after accounting forgravitational time delays, we find models that can reproduce the observedemission-line spectra and integrated CIV fluctuations. The models suggest athick disk BLR that is inclined by $\sim$40 degrees to the observer's line ofsight and with a emissivity weighted median radius of $r_{\rm median} =33.0^{+2.4}_{-2.1}$ light days. The kinematics are dominated by near-circularKeplerian motion with the remainder inflowing. The rest-frame lag one wouldmeasure from the models is $\tau_{\rm median} = 36.4^{+1.8}_{-1.8}$ days, whichis consistent with measurements based on cross-correlation. We show a possiblegeometry and transfer function based on the model fits and find that themodel-produced velocity-resolved lags are consistent with those fromcross-correlation. We measure a black hole mass of $\log_{10}(M_{\rmBH}/M_\odot) = 8.31^{+0.07}_{-0.06}$, which requires a scale factor of$\log_{10}(f_{{\rm mean},\sigma}) = 0.20^{+0.09}_{-0.07}$.
