The Deputation is the 43rd episode of Thomas & Friends.
Heavier than normal snow has fallen on the Island of Sodor and while the other engines hate it, Donald and Douglas are used to the conditions and clear the lines. They soon encounter one snow drift which is deeper than the rest. Just as they are backing to charge it a second time, they hear a whistle and find Henry nearly buried; they promise to get him out.
Henry is rescued and returns to the shed, but both Donald and Douglas are upset. They know the Fat Controller will be returning soon and after backing into and wrecking a signal box and destroying the Spiteful Brake Van between them, are worried that he will send one or possibly both of them away, which would lead to them being scrapped. The other engines agree that Donald and Douglas both deserve to stay and decide something has to be done; however, no-one can think of what.
Percy talks to Edward about the situation and he suggests that the engines nominate someone to talk to the Fat Controller, a deputation. Percy relays this to the others that they need a "disputation" and they agree to this. After a long silence, Gordon nominates Percy to do the job, much to the latter's horror.
The Fat Controller returns and a nervous Percy stammers through his speech about allowing the twins to stay. The Fat Controller catches on that Percy is a deputation and tells him he understands.
Later in the sheds, the Fat Controller responds to the engines' request. He begins by telling them that, although he understands their feelings, he does not appreciate them interfering with his decision making. He then surprises everyone by awarding Donald and Douglas with new coats of paint as a result of their good work in the snow, and announces that their names will be painted on them and warns them not to make any further mistakes. The engines realise that the Fat Controller is allowing both twins to stay and overjoyed, drown out the rest of his speech with happy whistles.
