This came to me out of the blue.

While on a mission, Lloyd disappears, to where, no one knows.

It's rumored he died
It's rumored he's in cognito.
Many rumors are floating around but the one that's most likely thought of,

Lloyd Montgomery Garmadon, the green ninja, is dead.

Well, one day, in the city. Kai, pushing seventy, gets the surprise of a life time

Should I go with it, let me know in the comments.
