Lona, 16.
Don's adopted sister Lona always had something to prove alongside Don. She keeps herself busy to avoid processing her complicated feelings about her place in the world.
A retro geek at heart, she's up to date on all the latest improvements to AR, but also loves to wax nostalgic about the older suits, VHS players, and even the vintage car on their property that doesn't currently run. Her belief is that she's the only one who has all of the information, and gets frustrated easily when others can't keep up. Her loneliness peaks when she sees others living their lives based on emotional reactions rather than facts and logic.
She cares for Don very much, but doesn't trust that he's capable of making the right choices without her explicit instructions. In this way, she attempts to control every element in her world. If it's broken? She can fix it. If there's a new game mode? She's read every patch note.
