All members are rescued, the ship's been fixed, the dimension is collapsing, the entire map has been explored. However, the crew insists we "agreed" on finishing exploring the place. "Who knows what we'll find?"
Does the crew need all 20 trinkets to be convinced we've seen all there is to see of this collapsing time-space discontinuum, so we can move along and do whatever it is we were doing?
I do have 15/20 trinkets, but yes, the five missing trinkets are all the hard ones.
