Ed Crowborough

From Tardis Wiki, the free Doctor Who reference

Lieutenant Ed Crowborough was a member of UNIT and the Sentinels of the New Dawn. Two years after completing his UNIT training, shortly before 2014, he accessed the UNIT archive and found that Liz Shaw had had dealings with them in the early 1970s. He interviewed her and learnt of Teri Billington, her particle accelerator and the events of the averted timeline, which he reported to Richard Beauregard. (AUDIO: The Sentinels of the New Dawn)
