I mean, think about it. Doll brutally murdered 5 classmates simply to facilitate her revenge plan. We see her having sadistic smirk while doing so. During prom fight she murdered another classmate simply for not leaving her way fast enough, and another one for no reason at all. And presumably she killed many more for oil.

Meanwhile, when Uzi entered her home and very noticeably started to notice suspicious stuff, Doll didn’t kill her immediately (which would be entirely in character), and seemingly just tried to lock her in… And when Uzi intervened in her attempt to kill V, Doll asked her about this, instead of simply attacking. Also notable that she is one of only two people in her class (other being Thad) who bothered to remember Uzi’s name.. Later, she simply restrained Khan instead of killing him, and agreed to left Uzi alone after getting Keybag. She even expressed her respect to Uzi. And while she tried to kill Uzi and others in the lab (notably, Uzi looked betrayed), after being critically wounded she encouraged Uzi to fight.

Considering that their mothers was best friends, it’s entirely possible that they used to be childhood friends (some even headcanon them to be honorary cousins).

So, history of drones’ hair is really unclear, and that make it interesting. In flashbacks from ep1 we see drones being hairless, and james comment in ep2 suggest that Tessa giving wigs to them was something unusual. Them adopting this method of individualization post collapse make sense, they picked a lot of humanity traits.

On the other hand, drones in the labs already had wigs before collapse. Possibly for easier identification, as they weren’t just regular workers, researchers needed to know each one. It’s possible that some other drones with specialized roles could receive such individualization, which might be what brought this idea to the rest of dronekind post collapse. Then again, james comment imply that it wasn’t usual practice at least when Tessa found cyn. I have two theories that can offer explanation.

First, this practice was inspired by hair of disassembly drones. Unlikely, but not impossible.

Second headcanon, some reporters, while visiting event in Elliots’ manor, noticed wigs of alphabet trio, and spread this idea, creating new trend.

In any case, Tessa being originator of modern drones culture would be cool :D

Looking how in this (link) commercial he was eager to touch Uzi’s organic hand, and at least one of his inner voices seemingly liked it… XD 

I mean, back in manor he drawn himself and V as lizards, adored dogs and tried to befriend crows. Then, he was again Uzi’s plan to attack humans in ep.2, was horrified by Earth destruction, and by vision of himself massacring humans on Earth. Remember, he was introduced drinking from severed head, and killed multiple drones with zero hesitation. He did it for decades. And show little emotion toward death of drones…

It seems that he really like organic life. Then again, one of his closest friends was human, which isn’t the case for most drones.

They used quite a lot of tricks to sell “Tessa” deception.

This is single moment in the whole show when we can see them standing straight side by side, and it’s hard to notice without slow mo. No wonder many people didn’t notice that “Tessa” was shorter than N.

And then her helmet, which is noticeably larger than human head (as cyn’s head should have fit inside), but she surrounded by drones with comically large heads, so don’t stand out. The fact that her visor isn’t transparent hide the fact that her face should be in bottom part of her helmet, while hat not only make her silhouette taller, it further makes viewers subconsciously assume that it is her head.

Add her wearing high-heeled shoes inside thick-soled boots (I would add here certain joke, but don’t want to provoke mods), it’s almost impossible to notice that her body is just as small as Tessa had as a kid.
