The monster made a strange howling/hissing noise, probably telling his friends: hey, tasty demigods over hear!
Leo pulled a hammer out of his tool belt and hit it on the head. The thing seemed surprised; how dare his dinner bash him. Leo took this as an opportunity to hit him on the head repeatedly, until it dissolved into dust.
He was relieved for a moment, but then he heard a lot of noise nearby, no doubt more monsters.
"Okay, we've got to get out of here," said Leo. "Can you walk?"
"I'm not sure" replied Jason.
"Umm, that cut was the only thing, right?" Leo asked hopefully.
Jason shook his head. Of course not. The gods forbid they have that much luck
"My ribs hurt, it's hard to breathe, and I think my leg's broken."
"Just great. Can you at least stand up?"
"Uh, I think so…"
"You sure?"
"Well, we don't really have much choice. We have to leave, and you couldn't carry me or drag me out of here," Jason said.
Leo tried not to be offended by that, even though it was true.
"Okay then, lets go," Leo grabbed Jason by both arms.
"One… two… three!" he pulled Jason up to his feet, with surprisingly little screaming.
"Okay, so the camp is… this way," Leo said, and they started walking.
The "walking" bit turned out to be really difficult. Leo could tell that Jason was trying hard to keep his weight of Leo, but it wasn't working too well.
Even with his best efforts, Leo was still half-carrying him. And, as everyone probably knew, he wasn't very good at this. He was already starting to get tired.
Jason was getting taxed too, Leo could tell that it was extremely painful, and it couldn't be good for his health.
Not to mention the fact that they weren't moving fast enough to outrun their pursuers. Leo tried to pick up speed.
"Jason, could you possibly go a little faster? They're catching up to us," said Leo.
"I'll try," Jason answered, gasping hard.
Leo felt guilty even asking. He knew that Jason was going surprisingly well for someone with his injuries. He wished he could do this better. He also wished that the camp wasn't so far.
They were speeding up a little, but Leo wasn't sure it would be enough.
Leo was having a seriously bad day.
He was having a hard time keeping moving. His shoulder throbbed, and he was completely exhausted.
He knew Jason must be tired too. He was breathing faster, and putting more and more weight on Leo.
As if that weren't enough, it had started to rain. It had started as a light drizzle, but was now a full-blown thunderstorm. This was making the "running" even more difficult, now he could hardly see, especially since it had been dark out already, not to mention the ground was getting slippery.
They must have been walking for at least an hour. Then Leo tripped on a patch of mud, sending both of them falling.
Jason screamed once, and then diminished to a loud moaning.
"Okay, let's take a short break. I think we're getting ahead of them," Leo suggested.
"Kay," Jason replied.
Leo handed Jason the bottle of water. He noticed that his friend was shivering from the cold, and he looked pale.
Unfortunately, he didn't have time to look into this. They needed to keep moving.
"Okay, we have too get going," Leo said.
He pulled Jason, groaning, back to his feet.
"Come on, man. The camp's not much farther."
That actually turned out to be true. They walked for maybe another five minutes, and Leo could see a lit up building in the distance.
"Almost there,"
As they got closer, their friends in the building must have seen them too. Leo saw two of them standing by the doorway, and then one of them started coming towards them.
As their friend got closer, Leo could see that it was Percy. He could also see that he was carrying Riptide, somewhat threateningly. He must have thought they were monsters.
"It's just us!" Leo screamed. "Jason and Leo!"
Percy must've heard them, because he put away his sword and started running in their direction.
He reached them quickly.
"Leo, Jason, what took you so long, we've been waiting- oh gods, what happened?" Percy interrupted himself, after getting a good look at Jason.
"Long story" said Leo.
Percy took Jason by the other arm and helped Leo to get him back to the cabin.
Annabeth was at the doorway, knife raised.
"Whoa, what happened too you guys?"
"I'll tell you in a minute. Check out Jason. He's really beaten up. Then I'll explain everything."
