Broadfell Prison guard

From Tardis Wiki, the free Doctor Who reference

One of the many Broadfell Prison Guards who worked under The Governor and Miss Trefusis. She worked alongside Lucy Saxon in killing the Master. Whilst Lucy was imprisoned, she held the potion which could kill the Master and when the revival ceremony took place, she passed it to Lucy and she threw it at the Master, killing all (par the Master) in the Prison.
