Denjiro: I understand that it was Oden-sama's announcement but
Denjiro: It's different, that was...!!
Kinnemon?: Kin-san?
Denjiro: (Talks about the piglet incident)
Kinnemon: Eh
Kinnemon: There is only person who knows that is

Denjiro:—but Kin-san, you’re indeed a smart man!! Lord Yasuie’s drawing is telling us to put 2 lines on the belly of the viper that represents Habu Port. These 2 lines means to erase the belly of the viper, in order words, “erase the words”!!
You told everyone just the part about the “two lines” because anyone who heard would’ve known that it means to erase the words in the middle of “ha bu mi na to”(Habu Port), which leaves us with hato(seawall).

And the spy would just pass that information on to Orochi!!
Kanjuro: Huh?!!
Denjiro: Kin-san!! As expected of our leader!! As I thought, you’re a man worthy of respect!!

Kin’emon: (so you’re supposed to read it as Hato[seawall], not Tokage!!!)
