Biography
- "You realise that I am on my way downstairs to interrogate your wife, Cattermole? In fact, I’m quite surprised you’re not down there holding her hand while she waits. Already given her up as a bad job, have you? Probably wise. Be sure and marry a pure-blood next time... But if my wife were accused of being a Mudblood — not that any woman I married would ever be mistaken for such filth — and the Head of Department of Magical Law Enforcement needed a job doing, I would make it my priority to do this job, Cattermole. Do you understand me?"

On 2 September, 1997, Reginald headed for the Ministry not only for work, but for his wife, who was to be tried by the Muggle-Born Registration Commission, as the Ministry had been taken over by Death Eaters and Muggle-borns were being persecuted. Outside, Reginald met Mafalda Hopkirk, who was actually Hermione Granger disguised by use of Polyjuice Potion. She gave him a Puking Pastille, and when he started to vomit, she took some of his hair. Reginald still tried hard to get into the Ministry, desperate to be by his wife's side, despite repeatedly vomiting and being unable to walk straight, but Hermione advised him to go to St. Mungo's. After being unable to stand any longer, he finally Disapparated.
This was all part of Hermione Granger, Harry Potter, and Ron Weasley's plan to access the Ministry undercover. Hermione transformed into Mafalda Hopkirk, Ron used Reginald's hair and Polyjuice Potion to take on his form, and after Harry took on the form of Albert Runcorn, the three headed into the Ministry.
Reginald returned to the Ministry, pale but no longer ill, just in time to witness Ron, Harry, and Hermione assisting in the escape of Muggle-borns who had been detained by the Muggle-Born Registration Commission, including his wife. Harry advised them to take their children and leave the country while Lord Voldemort was still in power.[1]
It is unknown if Reginald and Mary took Harry's advice, or what happened to them after the Second Wizarding War ended.
Physical description
Reginald was described as being a small, "ferretty" individual[1].
