Being stopped by Thorin, didn't stop Fili, unfortunately. All his eldest nephew DD was glare at his uncle, and yank his arm away from his grip. Walking towards Kili, he stood next to him, like he always did during their youth. 

The trumpets began to announce the Master as he steps onto a platform and the crowd cheers.

Back in the Masters house, Bofur is passed out drunk under a table when he hears the trumpet. "By my beard, is that the time!?", he shouted with slurred speech before he rises until banging his head on the table. He then rushes out to join the dwarves on the dock. "Wait!"

"Go now with our good will. And may your return bring fortune to all!", the Master announces before the crowd cheers with the company setting off on the barge down the lake. At the same time, Bofur pushes through the crowd, but when he reaches the dock, he sees the rest of the company has left, and is too far down the lake for him to reach. While this was happening, Saeril approached the remaining dwarves, and stood just behind the brothers, placing a hand upon Kili's shoulder, trying to sooth him of his despair. 

"I can't believe he would just leave us like that!", Fili growled angrily. Bofur looked to the side, hearing Fili's voice and smiled. "Oh, did you all miss the boat as well?"
