Summary
Blake Belladonna watches the ocean water as she journeys on a passenger boat. She repeatedly jumps at minor noises. The Captain of the ship approaches her, looking to befriend her and learn her story. He quickly realizes to his amusement that she'd rather be left alone. After he departs, Blake removes her bow and lets the ribbon loose on the water. She turns, not seeing the hooded figure watching her, or the moving scales in the water.

At her home in Patch, Yang Xiao Long watches the news on television. Updates are provided on the lack of access to Vale, the efforts to restore the CCT and Adam Taurus confirmed as present during the Grimm attack on Vale. Yang reacts to seeing Adam on the news and turns it off.

Taiyang Xiao Long returns home with packages, including a new state of the art Atlesian arm for Yang that General Ironwood had ordered be made for her himself. Yang is not particularly enthusiastic about it, saying that she would try it on another time and goes about her chores in the house. While cleaning a glass, it slips out of her hand, breaking on the floor. The shattering glass triggers a flashback of Adam, and Yang rears back. It takes her a moment or two to regain control. Her concerned father watches wordlessly.

Blake is just realizing that someone has been watching her when a sea dragon Grimm attacks the boat. She immediately goes into action, as does the boat Captain. The hooded figure is revealed to be Sun Wukong when he tosses his disguise to join in on the action. Blake is not happy to see him, but she accepts his help.

As the fight continues, the sea dragon reveals its hidden wings within its dorsal fin and attacks from the air, sending electric blasts at the ship and the two combatants. The Captain comes up with a plan, and together they take out the Grimm. Everyone on board the ship celebrates. Blake, however, wants answers from Sun after giving him a solid slap to the face.

Sun had been following her ever since she left Vale the night Beacon Tower fell. He figured that she was on a one-woman mission to attack the White Fang and would need help. Blake reveals that she is actually just going home to Menagerie so that she can think things through. For better or worse, Sun is coming along.

In Salem's Domain, Salem is coaching Cinder Fall, telling her not to let "it" sense her trepidation but to make it fear her. Cinder is clearly struggling with the effort to accomplish this. They are interrupted by the arrival of a Seer Grimm, which has a jellyfish-like appearance. It glides across the room, clearly unsettling Emerald Sustrai and Mercury Black who stand at the door.

After the Seer approaches Salem and she gives it her attention, Salem shifts her focus to Cinder. With a touch of temper, Salem demands that Cinder clearly tell her whether or not she did actually kill Ozpin. Cinder calls for Emerald, but Salem slams her hands down on the table and insists that she hear Cinder say it herself. Cinder manages to get out a choked "Yes".

After this, Salem orders the Seer to increase their forces at Beacon Academy. She is certain that "the relic" is there. Musing aloud, Salem wonders what an unknown person is planning.

Trivia

 * Sun mentions leaving his team to go on a boat before. This is likely a reference to his first appearance in "The Stray".
 * Sun also refers to accompanying Blake as a "journey to the east". This is a play on words referring to A Journey to the West, the origin story of his namesake allusion, Sun Wukong.
 * During the shot of the pistons of the boat, one of them has the letters RT inscribed on it, a reference to Rooster Teeth.
