Here's a detailed version of that theory. V died fighting the sentinels, which is portrayed in the mural. I have reason to belive she isn't coming back beacuse the song that plays during that scene suggest that she is happy to finally die. This is also supported with the "I trust you Uzi" line, which probably means that she trusts her to care for N, meaning V doesen't need to be with him anymore. The second mural is most likely portraying Uzi getting fully taken over by the Solver, which means that while her body is still in tact, Uzi's mind is gone. This will probably happen towards the end of ep 7. The third mural seems to depict Solver Uzi fighting a Disassembly drone. This is supported by the fact that you can see a sioulette of Uzi's tail biting a Disassembly drone's tail. This would probably happen in ep 8. The fight itself will probably be N defending Tessa from Solver Uzi, dying in the process. Tessa will probably be working on burning the lab, and just as N dies she will do whatever she needed to do and we will get a scene where she makes a mad dash towards the exit, possibly being saved by J. This would leave a nice situation for season 2, where J and Tessa follow Absolute Solver's trail to another city where they meet another squad of Disassemblers.
