This scene is suggesting about when a new comer "Hunter Gray" tells Thomas that he believes that the "Achilles Tendon" is much more than jumping but of a kangaroo wandering amongst the precious lands. Some textual evidence is (Epstein 15) "Hunter has found that a longer Achilles Tendon allows an athlete ti get more power from what's called the "stretch shortening cycle." This clearly states that Hunter is showing about the positive sides about having this and that there should be nothin g to worry about but being able to jump or do stunts as of a kangaroo
In this picture it shows the length and how tall he is, comparing to others and with his Achilles Tendon, how he can do things very naturally and is naturally gifted. Some textual evidence is (Epstein 16) "Tendon length is not significantly impacted by training, but rather is a function of the distance between the calf muscle and the heel bone, which are connected by the tendon." This suggests is of why Achilles Tendon is such of good use to humans who have it during high long jumps?
In this final scene this suggests that just because Thomas has Achilles Tendon does not mean it will go through in life with him as championship because anything can change even if you work for it. All that Thomas is suggesting that practice and hard work get the job done, not what you think you have and can't be. Some textual evidence about this is (Epstein 17) "Thomas debuted on top and has not progressed. He seems to contradict the deliberate practice framework in all directions" Meaning that none the less that Thomas as been relying too much on what he had that he forgot that it wouldn't hurt to practice.
