A recent & quot\;firewall"\; proposal claims to have settled the black hole infor mation paradox. It suggests that an infalling observer is expected to enco unter high-energy quanta in a region near the horizon. The fate of the obs ervers or the very existence of the &lsquo\;&rsquo\;firewall&rsquo\;&rsquo \; itself is still up for debate. Leaving those aside\, we are interested in understanding observational signatures of the &lsquo\;&rsquo\;firewall& rsquo\;&rsquo\; at the classical level. With this motivation\, we consider a reflective &lsquo\;&rsquo\;firewall&rsquo\;&rsquo\; just outside the ev ent horizon of a Kerr black hole. I will discuss the results of our model and imprint of the &lsquo\;&rsquo\;firewall&rsquo\;&rsquo\; leaves on the emission-line profile of a radiating Keplerian disk. The optical appearanc e of the black hole-accretion disk system will also be discussed in this c ontext. \;
