26 (The Kingdom of the Blind)
From Tardis Wiki, the free Doctor Who reference
26 was worried about her friend 15 when Bernice Summerfield could hear her in her mind. She was telepathic and told her about the Monoids. She helped Benny find the Halyvon ship. She explained the Halyvon nature and helped them find the telepathic nature. (AUDIO: The Kingdom of the Blind)
