What did Earth See Before He Died?

Storyline

4 close friends look for a photo of "Earth". A roommate who recently died to post a condolence, but instead finds a photo that reveals his panicked face. This is completely different from his normal personality. While Om recounts the incident on the day of the photo shoot and accidentally reveals that "Mon" stole Earth's pressure medication and caused his death. A conflict erupts. Before Fern reveals the truth, the incident in the photo has nothing to do with Earth's death.
