@Joggy sure 🙂 “someone’s talking but I trust you” = someone is telling our secrets / leaking information, but I don’t think you’re that person
“You’re a John not a Judas”. This is a reference to the Christian bible. In it, Judas is one of Jesus’s followers who betrays him, and John is one who is loyal. “Judas” is used a lot to mean “traitor” or “betrayer”.
