What orders does Gene take from Finny at the "decathlon"? How does he feel about it?A Separate Peace by John Knowles

In Chapter 9 of A Separate Peace, Finny pulls Gene farther
and farther away from the other boys who voices opinions on the war in the butt
room:

Only
Phineas failed to see what was so depressing.  Just as there was no war in his
philosophy, there was also no dreary
weather. 

So, he creates the
Winter Carnival.  Like the Olympics, the Games must have fire.  Gene senses that he is
acting as the Chorus, so he repeats the words, "Fire, fire."  Then, Gene calls out that
Gene Forrester is going to run the decathlon. At this announcement, Gene
narrates,

It
wasn't cider which made me in this moment champion of everything he ordered, to run as
though I were the abstraction of speed, to walk the half-circle of statue on my hands,
to balance on my head on top of the icebox on top of the Prize Tale...--for on this day
even the schoolboy egotism of Devon was conjured away--a wreath made from the evergreen
trees which Phineas place on my head.  It wasn't the cider which made me surpass
myself, it was this liberation we had torn from the gray encroachments of
1943, the escape we had concoted, this afternoon of momentary, illusory, special and
separate
peace.

 More
than anything, Gene delights in the escapes from the grim reality around them that
Phineas is able to create.  Indeed, like the oracles of old--the name Phineas means
oracle--Finny says something will happen, and it does; his powers
seem divine, infallible.  It is this ability of Phineas to create a world to close out
the grim world that encroaches upon their youth that Gene holds in reverent and loving
awe.

It is clear that when Gene returns to the Devon
school, he returns to recapture whatever he can of this world created by Phineas that
gave them such "a separate peace," a peace from that something inside man which was
"something ignorant in the human heart," about which Gene learns after having fought in
the war.
