Krypto's loyalty is tested in "When Jimmy Olsen Stole Krypto from Superman", a title that's a big lie, but not the last the story will tell. And it starts during a sleepover at the Fortress of Solitude, where Krypto sleeps in his very own basket.
Krypto is in another story in this issue, but this one ISN'T a dream. See if you can spot the difference. It's the follow-up to the one where a piece of Green Kryptonite is narrator; in this one, it's been turned red. At first you think Krypto's not really going to matter because his only job is delivering homemade diamonds to charities.
