Samuel was a projection created by the sentient Hive Mind Bacteria when 2262 when Lyta Alexander and G'Kar arrived on the "Hive Mind" planet.[1]
Samuel claimed to be a telepath who was part of a colony of free telepaths. He claimed that most of the crew of dead Psi Corps mothership had decided to abandon the Psi Corps. Lyta found this to be suspicious, but was walking amongst her life long dream of free telepaths. Samuel explained that the colony had rules about unauthorized scans, knowing that Lyta would not scan anyone without permission. After a surface scan of someone claiming to be Nathan Delcompte, she discovered the truth.
