Being a seaman, Hamadou Diom can mostly be seen among the other seamen, doing general labor. Diom was holding passenger Chioh Tan still for questioning when a spike shot by a siren penetrated Tan and also hit Diom, killing him.
The East India Company insurance assessment on the Obra Dinn incident praised Diom for exceptional performance of duties. His estate was unknown so £25 worth of outstanding wages and reward were donated to pension fund.
Diom's face becomes unblurred as soon as the player has uncovered enough information to unblur both Alexander Booth and Winston Smith, even if the player has not yet encountered Diom himself in any memories. This is due to his dark skin tone; since Diom is listed in the manifest as being from Africa (Siera Leona), and thus must correspond to an individual with dark skin, he can be identified by process of elimination. Although Diom's skin tone may not be immediately apparent in the Under Way sketch, it's much more clear in the actual dioramas.
Alternatively, Diom can be identified after identifying almost all other seamen. When only seaman Alexander Booth and Diom are remaining, the two can be told apart by Booth's English accent in The Doom, part 1. Diom's hammock (#55) is not present in The Doom, part 2, implying that he perished before that.
Diom wears an earring in his right ear. Earrings were not common among European sailors in the 19th century, but body piercing is tradition in some African cultures. This hints to Diom being from an African country.
