In "A Tale of Two Cities" he said that it only took two hours for the polar bears to figure out the cage feeder puzzle. The polar bears escaped during the collapse of the DHARMA Initiative, so he was part of it. In The Hunting Party he quotes Alvar Hanso. In "LaFleur", a DHARMA mechanic with the name of Tom is shown. Sawyer asks him where to find Juliet when Amy was giving birth. He looks very much like a 30 years younger Mr. Friendly.
