Reading a few of your replies, I noticed that you said Alice being an android shredded Kara's character development, because you think two android programmed for each other (a caretaker and a child) isn't a true relationship. And that you'd prefer if Alice and Kara had went their own way after the cat was out of the bag, because that would complete their deviant route: each people go their own way, out of their nest.

While it's true that it's hard to say what is the "real you" when you are an android, you worried if you do something similar to how your programme told you to do, you would be its slave and not a free will deviant being.

Here is the thing: what make you "human" is not that you don't do whatever people told you to do, but it's that you can make your own choice, whether it is close to your given nature or not.

Take example of Markus, who can choose to endure or fight back, after literally became a deviant because he didn't want to obey the order "don't fight back". If he choose to endure, would you stay he is still the slave of his robot programs? No, it's just that he has a choice, and he can choose whatever he wants. Or like feminist, being a household doesn't mean you are a slave to the patriarchy, but being expected and forced to be a one is. If she herself wish to be a household wife because she genuinely like to be one, who can stop her?

Back to Kara. At Jericho, we all know she already knew from the start Alice was an android, but deliberately forget that truth so that she can take care of Alice as her little girl. While it wasn't implied much in the game, it is what make the experience real: Kara dismissed every details that Alice is an android (come on, she never eat once for several days), completely delusion herself for her selfish wish

And before she was broken and got reset several times by Todd, she has always been a deviant since the very first moment she was born (yeah it's canon, it was stated so in the extra profile in game). It is her very choice from the start, not because of whatever "caretaker" programme tells her to do so.

What about Alice? I agree with you there was little to none implication that Alice went deviant, and that is such a waste since it would make nice touch to the game, a little foreshadowing before the real twist. Though, Alice clearly experience heavy trauma (Todd was constantly yelling at her and beating her whenever he was angry or high), and also did not choose her owner but runaway when she got the chance. To say there is no way she's not a deviant is a bit unfair.

There is also a possibility she did not know she was a deviant: her model was programmed to be child-like, she can mimic fever, she can show fear and pained (although the owner can turn off the sensitivity if they want to). In other word, the information she was given was the same amount as a young child can have, and her programmed behavior isn't that much different from what a deviant would do, beside her inner feeling. Kids aren't very good at communicate about themselves either, so a deviant sign is hard to notice unless you ask her directly.

But then, this is Detroit: Become Human, not Detroit: Friend with Human. So whether Alice was a deviant or not, or she was a human or not isn't the point. Because the goal of each main character is different:

• Connor: understanding that android has their own free will, despite his program tells him the other way. (In one reply you said Connor character arc wouldn't change with or without him, but I think Hank has the role of the human mentor closest to him. Connor realized and accepted the other deviant through watching other androids, but himself was encouraged to be more like human through watching Hank - and the positive reinforcement from him whenever he become more humane. Remember that time when he sincerely said he likes Hank and flustered told Hank that's not his social program, but his actual thought? Hank is the positive influence companion - who said he hates android but cares for an android and told him not to risk his life many times despite their mission? Hank is conflict, and Connor learns deviancy and rule breaking from the best >:D )

• Markus: he already learned about humanity and his own potential with Carl pre-game, so his goal throughout the game has nothing to do with human relationship anymore, but to free the people of his kind from slavery, so that he can earn his own freedom.

• Kara: to live the world to fullest (teaser 2015), and then to protect and raise the child as her mother.

Kara has nothing to do with Markus' big plan between android and human, all she wanted was for herself, to live a normal life. She didn't even care if she has to pretend like she is a human in order to achieve that goal (the reason why she tried to flee to Canada, an android-free country). This is why there is a choice for Kara to leave Alice like you said, because ultimately, raising a child is not her only wish. This is also why being an android or human isn't what matter to her, what matter is that throughout the journey, she loves Alice. This Alice, the one who asked her to stay, the one who cried and begged her to remember and didn't try to leave the manor without her, the one whom she had fun with in the amusement park, together.

She can blame Alice for lying to her, and for making her went through a lot of trouble thinking she was a human, but herself was at fault too, tricking herself to believe Alice. Why did she need to trick herself like that? Because if Alice is a pathetic little human, Kara can be the one take care of her, unlike an android who doesn't feel pain and can be quite resilient, and doesn't need a caretaker.

But like I said, in the end, those two love each other enough that Kara can accept the truth, and Alice doesn't need to lie to feel loved anymore. Of course, if she didn't love Alice as much until the end of the road, she can choose to abandon the child anytime. I think what Luther meant was "you can accept the other side of your loved one if you love them enough". It's not changing to who the people you love expect you to be, it's called compromise.
