Solara
From Tardis Wiki, the free Doctor Who reference
Solara was Edwin's assistant and was the only person to recover from a Toraxian sting. She helped the Sixth Doctor to discover the source of the insects. She asked if she could come along with the Doctor and Constance Clarke. She started to become worried when her mind started to be affected by the Toraxians. Looking for the other colonists, she started to transform. (AUDIO: Colony of Fear)
