The hint is possibly more vague than it probably should have been on the Raven-Man card.
Don't resolve either of the scripts written on the card - add them together and resolve s.569
If you get card F (by spending 6 story tokens) you can see the full text at the bottom of his card telling you to: "Try to connect both these paths. Do you guess how?" whereas if you get card G (by only spending 3 story tokens), the words at the bottom are obscured and you don't get that hint.
