So here is a somewhat big one. Heracles tells them that if Jason and Piper contact their friends, he will kill them and sink the ship. So as they walk back to give them the horn, there is this little line:

"Too late to reconsider. [Piper] already sent an Iris-message to Leo."

Does an Iris Message count as contacting someone?
