Flemming

Flemming is the maitre d' aboard the Starship Harmony and Redemption.

He helps River Song to deadlock seal the baggage hold containing the TARDIS (and the body of Hydroflax), leaving her and the Doctor free to visit the restaurant and sell the Halassi Androvar lodged in Hydroflax’s brain. Unfortunately, using Ramone’s head, Hydroflax’s body is able to trick Flemming into opening the hold and faced with the prospect of losing his own head. Flemming makes a bargain with the body of the king. If the cyborg spares his life, Flemming will tell him all he knows about the real husband of River Song and help him to track the head of the the Doctor.

Having betrayed River, Flemming leads Hydroflax’s body to her and steals her diary hoping to use it to his advantage. However, River hasn’t chosen this starship on this particular date for nothing, and has timed her arrival perfectly so that when a meteor strike hits, only she and the Doctor can make their escape.
