Caption: Figure 5.

G395H/F290LP spectrum covering the He Iλ10830 and Pa-γ emission-line complex. A clear absorption feature is visible in both the 2D and 1D spectra, indicating the presence of dense neutral or partially ionized gas along the line of sight, likely located in the nuclear region close to the accretion disk and/or the BLR.
