Erin Lewis
From Tardis Wiki, the free Doctor Who reference
Erin Lewis joined the Church of the Outsiders some time before Ianto Jones. Her father did not "get" her interest in aliens or her involvement in the Church. She was hopeful that alien races would be kinder and better than humans. She gave Ianto a tour of the commune after he joined and was assigned as his co-pilot, detecting that he had spent a lot of time around aliens but assumed that they were hiders. (AUDIO: Believe)
