After noticing the edge of what looked like a safe, hidden behind a drawer, Daniel approached the area, and pulled the piece of furniture away from the wall. It was only then, that he found out that the metallic bar wasn't part of a safe, but was in fact the edge of a glass case which contained the spare key to control the helm.
With joy beaming from his face, he quickly opened the small glass panel behind which the key was stored, and took it. He then walked out of the cabin, and along with Jerigh and the woman, went back towards the bridge in complete silence.
Once they reached the bridge, Daniel took the key out of his pocket, and showed it to the woman, which confirmed that it was in fact the right key, by saying "That's it."
