CALYPSO
Calypso looked down,riding on Festus was totally usual but the weird part was Festus had a son. A SON. Totally weird but the story behind that was Festus was totally damaged so Leo had to build a smaller mechanical dragon to keep Festus charged. It was temporary but Festus liked it,so they would probably keep it even after Leo fixed up Festus.
No one other than Leo and Percy had met Calypso so it was quite interesting when Piper and Jason exchanged words with Calypso. Apparently,Jason flew himself and Piper over after finding out that Leo and Calypso were in California.
