Inspired by a Leaked video from the 90s, which allegedly shows a Grey alien in an interrogation room, located somewhere in or around Area 51--specifically, I believe, either in S2 or S4.

The alien in the video, known as EBE2 (extraterrestrial biological entity 2--2 as this was reportedly, at the time, the second living alien secured by the US military), was apparently quite ill at this point, suffering from an infection of it's pulmonary/cardiac sac--as it's heart and lungs were a single organ. In the video, EBE2's condition begins to degrade, it is then looked after by medics present at the time, which this drawing depicts.
