Gordon is a big, grand, important engine.
He knows it. you know it. everyone knows it.
So if he wants a thing, naturally, he should be allowed to have the thing... Even if the thing is like, several barrels full of wine and a hopper full of sugar cookies from last night's winter festivities.
Henry gets a good giggle out of this, of course, and a bit of a nuzzle to remind this Massive Baby that all is well and the discomfort will pass.
My favowite big twains being big gay twains, as promised XD i'll do a smooch soon but i think it might be a smooch in their human forms so i can REALLY GO HAM ON THE GRABBING.
