After the events of an adventure where Rick and Morty are seeking out a purple cube (which results in the death of their assistant Chachi), Morty reminds Rick that he was promised a dragon. When Rick tries to brush it off, Morty brings up how he agreed to help with the adventure in exchange for one. Irritated by his constant demands, Rick sprays Morty with a gas which inadvertently knocks them both out and causes the Space Cruiser to start veering out of control as they head back towards Earth. After crashing, Rick wakes up in the hospital to Beth reiterating Rick's promise to Morty.
