Jalkis

Jalkis was a Suroban who captured the crew of the Seamancer. Unlike the other Surobans, he wanted to help the Tenth Doctor return to Earth. When King Alalal forbade him from doing so, Jalkis secretly disobeyed, and was wounded while protecting the Doctor from skilus eels. The Doctor convinced Alalal to let Martha Jones treat Jalkis' injuries, and to treat him as a hero, not a traitor. (COMIC: Shipwreck!)
