Soon enough it was time for Percy, Annabeth, Leo, Grover and Chiron to go back.

They all bid each other goodbye. Malcom was the saddest out of all of them as he cried.

When they arrived, they went filled everyone else in about their day.

And they took a few more days to relax. Then they were back to fighting monsters.

Days passed and one day in particular they got a surprise.

A portal appeared in the middle of the camp's dining hall. And familiar faces stepped out of it.

Malcom let go of Tony's goatee that he was tugging on, then ran and hugged Percy.

Percy, Annabeth, Leo and Grover rushed to hug the avengers. Chiron galloped over and gave Foaly a handshake.

"It's so good to see you guys again!" Leo shouted.

A shout interrupted them all.

"Is that Captain America?!"

Percy turned to Luke. "Yep and you're not dreaming!" He said, as he laughed with everyone.
