Lionel Carson
From Tardis Wiki, the free Doctor Who reference
Lionel Carson was an old friend of Sarah Jane Smith.
Sarah Jane met Lionel at the demonstration of the serfboard, where he expressed a dislike for modern computers. After the demo finished he suddenly developed a liking for the serfboard, due to the hologram of Joseph Serf hypnotising him.
Lionel was also present at the launch for the serfboard,and met Clyde Langer and Rani Chandra, who were disguised as editors of a magazine. When Luke and Sky modified the hologram so it hypnotised the audience to destroy Harrison's pen, Lionel stepped forward and smashed the pen underfoot, freeing the Skullions.
