Home was an empty lonely place. Before Lapis ran away, it was filled with her dark brooding and self pity. The blue gems' gloomy nature drove everyone but Steven away. It was out of the way and the gems did not like Peridot using the warp pad without their permission. They barely tolerated the two Homeoworld gems anyway. That left Peridot spending her time trying to amuse and comfort Lapis.
It all changed when Steven came back after being abducted by Homeworld. Peridot was hurt that the Crystal clods did not seek her help let alone tell her what had happened. Lapis had a different reaction. Upon hearing that Steven had defied the Diamonds the blue gem panicked. She flew off back to space, leaving Peridot alone.
Now the barn was an empty, broken place. The cold wind blew through the holes that Peridot could not repair for fear of waking Lapis. The equipment was next to useless meaning Peridot couldn't repair the barn even if she wanted to. All Peridot had left was time and a pet that obviously liked Lapis better than her. But things got better, a new visitor came to visit, Pumpkin was more affectionate and with Steven's help the gems sent her on more missions.
Finally Peridot lost even that. It was a sunny fall day, Peridot was looking forward to a new mission when Onion walked in.
"I'm sorry Onion, I can't play with you today. I have an important mission with the gems," said Peridot.
With that the green gem stepped onto the warp pad. Onion frowned angrily. Later that evening, after an exhausting and dirty mission Peridot found the barn on fire. It's flames had already consumed most of the barn as it collapsed right before her eyes. Not missing a beat Peridot stepped back onto the warp pad.
An angry Garnet glared down at the dirty gem. Peridot merely waved.
"Hi, look my barn just burnt down can I relocate to the temple?" asked Peridot.
Because Steven was on one of his dates with Connie there was nothing stopping Garnet from refusing in her way. In dusk's light a small green form could be seen flying out of the beach house's window. Peridot landed messily on the sand.
"I'll take that as a no then," said Peridot as she dusted herself off.
She spent the night sleeping in the Claw Crane with several green stuffed aliens at the Funland arcade. The next morning she was awoken by the crab claw pulling at her head. With a shout Peridot jumped out of the holding box and ran off. She wandered the town, her mind spinning about questions about what she would do when she saw the answer right on the newspaper box.
There in large, bright letters it said: Are you the next hero? Justice League looking for new members.
Peridot read on: Are you the next hero? Do you have untapped potential such as special abilities or skills. If so this could be you. Find out now.

Peridot smiled that sounded exactly what she was looking for. After interrogating a passerby Peridot ran back to the farm. The place was a ruined mess but maybe she could salvage something.
The next morning Peridot drove off to her destiny on a floating tractor, leaving Beach City far behind.
