Friends to the End, Part One

A new arc begins. Word reaches Finn and Jake that Billy, the greatest hero Ooo ever produced, has somehow reappeared inside the Computer Kingdom. Eager to prove he's more than just a kid with a sword, Finn races to meet him, but the figure waiting there isn't who he claims to be, and Computer Princess's past is about to catch up to her. Kenzie Bugg (Tuca and Bertie) joins writer Nick Winn for the start of Friends to the End.
