Question 664: Who's scared of her?

The Dreadnought Hoax, perpetrated by Horace De Vere Cole involved Cole and five friends—writer __X__,  brother Adrian Stephen, Guy Ridley, Anthony Buxton and artist Duncan Grant—who disguised themselves with skin darkeners and turbans. The disguise's main limitation was that the "royals" could not eat anything or their make-up would be ruined. Adrian Stephen took the role of "interpreter".

In Weymouth, the navy welcomed the princes with an honour guard. An Abyssinian flag was not found, so the navy proceeded to use that of Zanzibar and to play Zanzibar's national anthem.

Thus began one of the most famous hoaxes in history, which exposed the incompetence of the British Navy.
The "royals" inspected the fleet. To show their appreciation, they communicated in a gibberish of words drawn from Latin and Greek; they asked for prayer mats and attempted to bestow fake military honours on some of the officers. This was origin of the phrase __Y__

So:

1) ID the missing person
2) WHat phrase, which gained notoriety in the past 2 years, finds its origins here.

ID the person on the extreme left.
