Alex is Harriet Jones’s right hand man. A job he claims he likes. He seems devoted and attentive to Harriet, sticking with her as she is transported to the Sycorax ship. The Doctor uses Alex to ‘punish’ Harriet for destroying the Sycorax ship. He whispers his ‘six words’ to him. What he did with the six words is not clear, but it took only a few hours for Harriet’s premiership to be questioned.
