Hologram

The Hologram was an automated support device used by Time Agent Mary Windsor, reprogrammed by a figure from Mary’s past in his image before his apparent murder at her hands. He offered strategic advice, taunted Mary over her emotions and doubts, and was later transported with her to Stormcage following her surrender.

Given his voice, constant sexual references and use of phrases such as ‘eye candy’, as well as the Doctor’s description of ‘the flirtatious [Time Agent] in the red jacket’ whom Mary identified as her mentor, it can be inferred that the Hologram was actually a representation of Torchwood’s Captain John Hart, however this is never confirmed within dialogue.
