Steven and Phoebe Chapter 11

Steven and Evan sat next to each other in depression. Fionna walked by with a surf board.
"Howzit... Evan?" She said.
"We've been having a bad day." Answered Steven.
“Hmm, maybe surfing could cheer you up."
"I think that's a great idea." Replied Evan.
The brothers, pet, and Fionna then started surfing, though Phoebe was a bit nervous. Fionna grabbed Steven and put him on her surfboard. Phoebe watched the two surf. She was pleased, but Evan kicked Fionna off her surfboard. Steven looked underwater to see the blonde girl.
Evan then started surfing on a wave without falling off the top of the wave. Fionna tried to beat Evan, with Steven still on the board. The two fell overboard, but Phoebe enjoyed it. Phoebe saw the two brothers swim under her board, but she was still nervous.
----------------------------------------------------------------- 
The three humans decided to take a break and build a sandcastle. Phoebe buried her legs under the sand and put a leaf on her castle in place of a flag, but it wasn't fun at all. She then asked Steven if he wanted to surf with her.
------------------------------------------------------------------------------------------------------- 
"Oh I can't complain, mom." Said Double D, talking on his cell phone. He and Dexter were spying on Phoebe from a palm tree. "I'm camping out with an evicted criminal and had my head chewed on by a monster!"
"Something is not right." Said Dexter. "2-1-3 is returning willingly towards water." Suddenly, Double D felt another phone call: it was Mr. Harriman!
"Mr. Eddward," he said. "I am getting impatient with you both. I want a status report."
"Oh, things are going well. Aren't things going well, Dexter?"
"Why would she risk drowning?" Dexter asked himself.
"Dexter? Help me out here." Pleaded Eddward.
"I would've expected you back by now with 2-1-3 in hand." Said Harriman.
"Well, there's just a few things left to pack, and we'll be..." Dexter put down Double D's antenna on his phone.
"Hang up." Said Dexter. "We are going swimming."
---------------------------------------------------------------------------------- 
Steven, Evan, and Phoebe were once again surfing. Phoebe was scared at first, but then she started to enjoy it. Suddenly, Dexter popped out of the water and snatched Phoebe! Fionna saw Evan and Steven crash, so she decided to help them. Dexter got hold of Phoebe, and, since she can't survive in water, she held onto Steven.
"What happened, Evan?" Asked Fionna.
"Phoebe was drowning and dragged Steven down with her!" Replied Evan.
Fionna swam down to rescue Steven, but not Phoebe. Phoebe managed to escape Dexter and Eddward by making a hole Double D’s air tank, sending them flying.
Fionna managed to rescue Phoebe, but when she woke up, she started growling. This was noticed by Dana Tabes.
"I know you're trying," She told Evan. "But you have to think about what's best for Steven, even if it removes you from the picture. I'll be back tomorrow morning to pick him up."
"I really think they had a chance." Fionna said to Phoebe. "Then you came along."
Author's Note: I am aware that Fionna might be afraid of the ocean, like how Finn, Fionna's male counterpart, is afraid of the ocean, but since this story is set AU, I get to make up some of the rules.
