Lizzy set about working on the programs for the doppelganger AIs you stole from the Sands Gala, and you discovered something… interesting. And by interesting, you mean infuriating. Despite following the plans and compiling the data successfully, the resulting bots were nowhere near the level that Sinatron was! In some ways they were better than Norm Prime, but in others, even he seemed to have them beat. Clearly, there's something you're missing. They were still leaps and bounds above your current AIs, and they're certainly going to be useful, but there was always something that held them back from the sort of fully autonomous, emotive intelligence you saw displayed at the Sands. You just don't understand, the code is the same in every way!
When you tried to put them into isolated systems to see if they would do better without having to run actual hardware, you were surprised to find that it made them even worse! In a relative sense, of course, but for some reason the mere act of putting the adaptive AI protocols into a specific physical chassis rather than keeping them purely digital seemed to improve their responses.
You now have the means to make highly convincing physical robots to masquerade as other people. Very useful. But the vexing uncertainty of just what is missing dogs you! You must crack this somehow, you must!
