When the story ends
Loner
At the end of the adventure you may add another trait to the character. It is better that this is related to how the story just ended and can be either a Skill, Gear, a new Frailty, or even a new Nemesis! You can also modify an existing trait to better represent an enhanced expertise.
Also update the list of NPCs, Locations, and Events that may show up again in future adventures.
Example
Zahra secures the datapad in the hands of the authorities, framing both Wethern and the Leton Corporation. Wethern is arrested, but she has gained a powerful enemy working against the Corporation. She gains "Wannabe Hacker" to her skills. Maybe Melina can mentor her!
