Mederan was especially loyal to Zin, never leaving his side, and as such was the last to go through the wormhole onto the train that was heading for Chicago. However, due to no other human 'hosts' left to take and, in a touch of irony due to his loyalty, Mederan was forced to take the life force of a Guide Dog that was been taken to Chicago for a young blind man called Stan Roberts. Although initially free, Zin presumably told one of the fugitives to take him to Stan until he was needed.
