Let’s start with the VHS tape first it’s just to tell us why disposing drones in the right way is very important but the human ignored this anyway and as we can see at 9:50 any drone who is not properly disposed like Cyn, V, N and j has 0.001% chance of self rebooting and the thing you missed is at 10:31 we can see that 70.3% chance of no charges observed like what happened to N V and J when they rebooted and we have 0.7% chances of potentially hazardous mutations which is exactly what happened to cyn when see rebooted Now at 13:30 you missed this which is actually the absolute solver talking to cyn showing they are completely different entities as the solver is saying hello and how he won’t discard her so cyn can let it control her as the absolute solver said she will be there in a while which means cyn could be innocent but the solver is taking control of her mind making her the first host of the solver or user and most importantly they are at earth n j v tessa and cyn all at earth therefore everything starred at earth At 49:59 you didn’t understand the disassembly drones were created by cyn or the absolute solver to be more accurate yes cyn made them which means the humans aren’t the ones who sent them to dispose the worker drones in copper 9 and they are innocent but it’s cyn we kinda figured that out in episode 2 when Uzi said the humans sent them without a communication to earth and then N asked questions if j was getting ordered then from who and how? Since they can’t communicate which is actually cyn not the humans they were taking orders from also the disassembly drones aren’t completely robotic they have organic insides including j v and N alsothat the first thing cyn did to the humans is killing them therefore i dont think it would be very hard to know why she created the murder drones which also means that cyn is the one who created the landing pot so v j and N clones could reach copper nine but the weird thing is if tessa used the landing pots to reach copper nine seems suspicious right? But most importantly how did she even survived the gala massacre? Also if she really works for jcjenson I think they would give her very powerful weapons not a sword and revolver and i don’t think they can also make a disassembly j clone to help tessa At 58:20 you missed this important scene which is very important in the later episodes that explains why their memories were being blocked is because cyn is an administrator over v and N and j when she was around in episode 1 also that is a further proof that they were created by cyn. Also uzi made herself an admin over them which means cyn doesn’t have any access to them now which means that their memories are back

My guess is since N, V and now Uzi can fly they could get there pretty quickly and land behind them. Just a theory. As for Tessa shooting at Doll it's my guess she suspected that Doll was infected and had her suspicions confirmed when the bullet had its trajectory forcefully changed at the last moment. Hence Tessa saying "just checking" and Doll looking upset that despite her eyepatch hiding the Absolute Solver symbol from Tessa she found out anyway.
