Warning! SPOILERS for Upload season 2.
Upload season 2 finale saw Tinsley restoring Nathan's backup consciousness to the Lakeview system, meaning there could be two Nathans existing at the same time in Upload season 3. With Nora missing and a vacancy opening at Horizon, the inexperienced Tinsley has joined the team of employees responsible for Lakeview. While the character has evolved since her clumsy introduction, she may have made a big mistake at the end of Upload season 2.
Now promoted to a management position, it was Aleesha's role to train the new temp. With Ingrid apparently having been uploaded to Lakeview, the angels of the digital afterlife are having to work overtime to serve the most demanding character in Upload. The very fact that Tinsley, a temporary employee, was sent to work at the dinner party launched by Ingrid and Nathan was reason enough for one of Horizon's richest customers to place a lot of complaints.

After starting to have a crush on Nathan, Tinsley realized that Lakeview's most troublesome Upload was nowhere to be found, and the solution of then restoring Nathan's backup version into the system may have created two versions of the programmer. At the end of Upload season 2, audiences can see that a new avatar identical to Nathan's original one is being uploaded to Lakeview. There is now a Nathan in the real world — whose lab-grown artificial body was given Nathan's original consciousness — and a virtual Nathan in Lakeview. The problem for Upload season 3 is that the consciousnesses of both versions are technically the same, the only difference being that the original was downloaded to a body in the real world.
