The life of a high school kid can't be serious all the time.

Yes, once again Lane is under the pressure of knowing that even being in the top 2% is just a minimum starting point.
A location a distance from the optimum destination. Sure it's a long way from "Based Camp" but that last 1,000 feet up Everest are the most demanding.

So, sure it makes sense take a moment out to act silly before he to needs to take a deep breath and climb those last steps to the summit. 

So let the fun Begin.
