Kion's Lament is a song in The Lion Guard: Return of the Roar.
It is sung by Kion as he begins to doubt whether or not he is ready to lead the Lion Guard. The song is later resumed after Mufasa gives him some sagely advice, which leads Kion to believe that he is, in fact, ready to become the Lion Guard's new leader.
Why? Why even trust me at all?
They say the Guard is my call
But then come tell me I'm wrong
Now what? What should I do?
And who? Who do I turn to?
Now everything feels so upside down
Deep down, maybe I knew
It was way too good to be true
With all my friends looking up to me
Some leader I turned out to be!
Maybe my journey is far from done
They need a leader, and I'm the one!
So now it's time for them all to see
The lion I was born to be!
It is time, to take the lead on my own
It is time, for something bigger than I've ever known
An early shipping animatic of the second half of the song, dated 21st January 2015 exists, complete with an early/demo singer. It is almost identical to the final version, save for one notable difference: In the final, Kion walks straight past the water. In the early animatic, he glances down at it.
