Terry Jones
From Tardis Wiki, the free Doctor Who reference
Terry Jones was the younger brother of Eugene.
Profile
Terry apparently did not have a close relationship with his brother. He seemed very calm about the fact of his brother's death, and when talking to Gwen Cooper explained that his understanding of what had happened was that Eugene "walked into a road, and got run over". During the conversation, he also kept his attention on the television programme he was watching, and never once looked at Gwen. (TW: Random Shoes)
Behind the Scenes
Coincidentally or not, the character has the same name as Terry Jones, a member of Monty Python.
