This is in Keith's pov have fun.
(The real reason he left voltron)
It was another day at the castle.( Note that Im at season 4 so there is the castle still)  and us paladins of voltron were chilling in our rooms. Except me. I was training and listening to music. Lance walks by and hears Keith's music and decides to change it. He sneaks in the training room and finds the playlist Keith was playing. ( Lance knew because all the paladins use playlists and Spotify) Lance searches up a song to get at Keith. He finds the song and plays it. (Play the song above) I hear the new song playing and I can't consatrat. "Lance really? I know its you there." I said. I then starts running to the lions. He happens to run into Shiro. "Were are you going in such a hurry Keith?" Shiro asked. " Im going to join the Black Parade. " I ammited but Shiro grabbed me. "You are not joining the black parade Keith. Voltron needs you." Shiro gave his dad speech that I have heard alot. 'So if I quit voltron I can join the black parade' I thought. This is perfect. I can say Im doing training with the blade. They will believe me and then Ill go join the black parade. " Keith don't leave us we need you." Shiro said. How many more times is he going to say that to me.
Time skip to Keith leaving still Keith's pov
I was saying good bye to everyone and trying not to be excited about it. "Were going to miss you but its your dession Keith." Shiro said. "Group hug!" Hunk said. Everyone got there hugs and before I left my final words to them were "Im joining the black parade." Then I was off.
Third pov
Shiro was so mad at Keith for going to be join them. Pidge and lance were chuckling/laughing. Hunk shuged his shoulders and Allura and Coran were confused.
