There were plenty of protests, but finally the company listened to reason. One by one, they hid in the barrels on the barge. Fili found it impossible to sit comfortably. The way Saeril had acted was indeed worrisome.
Without any visual, he grew uneasy. "What’s he doing?”

Bilbo peered through the hole in the barrel. “He’s talking to someone. And he’s...pointing right at us! Now they’re shaking hands.”
Thorin's eyes narrowed. “What?”
Dwalin was ready to fight if necessary. “That villain! He’s selling us out.”
Just then, each and every barrel was filled to the brim with dead fish. 

Bard then went back to steering the boat, kicking the barrel nearest to him when the dwarf inside started squirming and making noise. "Quiet! There are guards ahead, we're approaching the toll gate", he brought the boat to a stop at the gate and nodded at the man who approached him. "'Ello Bard, anything to declare?", he was a senior-aged fellow, but overall a seemingly nice man. "Evening Percy, but I am cold and tired, and ready for home", Bard replied, handing over a tattered piece of paper to the other man, which he stamped and went to hand back to Bard. "There we are, all in order!"

Saeril kept her stance to act and look like a commoner, so no one would notice her as an elf. Using the hood to cover most of her face, she looked like a mysterious young woman. The toll gate was barred and it seems they do a thorough job of checking their goods. She also kept her presence near Yavanna, standing near her, while she sat on the bench.

Under his father's order, the kingdom had to be sealed off. Legolas began to walk towards the guards by the gates. "Close the gate! Keep it sealed by order of the King", he commanded under the Silvan tongue; one of the guards approached him, “Man os Tauriel? (What about Tauriel?) Edevín eb enedhor na gû a megil. En ú-nandollen. (She went into the forest armed with her bow and blade. She has not returned.)" Having to hear this, the Elven prince walked out, looked into the woods. 
[i]Tauriel, what have you done?[/i], he solemnly thought to himself.
