Behind the scenes
This president's real world counterpart is Donald Trump, although the connection was not made in this episode.

In the previous episode, set in a reality created by the Monks to resemble the real world almost perfectly, an unnamed president was a dark haired individual who did not have much physical resemblance to Trump. Trump's status as president around this time was confirmed in Arachnids in the UK.
