Sometime around late 2007 to early 2008, Thomas was working as a missionary in Maliku, an island off the coast of India. The Amazo docked at the port for supplies, and Ivo requested Thomas to come aboard the ship to administer last rites for a dying man. However, once he boarded, he was thrown in a prison cell and spent a bit over a year on the ship.
When Oliver Queen was captured for a first time, Thomas saw him come through. On his second capture, previously having escaped, he met Oliver directly. He told Oliver of his story, letting his rat, Abraham, run over Oliver. Not long later when the ship was hijacked, he was let out of his cell by Sara Lance. When Hendrick Von Arnim attempted to strangle Sara to death, Thomas knocked him across the head with a pole and ran for his life. Following this he swam to the mainland of Lian Yu.
