Actually, she was assimilated at 6 or 7.
And no. I don't think her behavior resembled that of a child.
Did she know that she could?
In "Human Error," she wasn't offered quarters until her implants were removed. This holodeck fantasy says a great deal about where Seven felt she belonged. She didn't think she deserved quarters because she wasn't "fully human."
People can love other people and still have preconceptions & prejudiced opinions about them.
ok at 6 then, which makes her even more of a child.
Human error was entirely a holodeck program, her "offer" of quarters was within the program
Seven designed the holodeck program. It shows the way she thinks about herself & her relationships with others.
Most clearly, it shows that she thinks of herself as not fully human and not deserving of the things she desires (quarters, privacy, companionship) until she is "fully human." The tragic thing about that is that she never will be.
This is hardly a child's development.
I think we often have a tendency to look at people in terms of age, and not look at them in terms of who they are on their own terms.
This is all, of course, my opinion. I hope you'll forgive me that it differs from yours.
