I liked Naomi, and found the introduction of the Borg kids distracted from the humanizing elements the relationship with Naomi had for Seven. I liked the idea that they shared a common home in Voyager and the Delta Quadrant as shown in 'Bliss' and Namoi's use of Borg designations, seemingly to rile mom, mentioned in the episode with the 3 severed borg. (I can't remember the episode.) They had a great relationship that might have been explored further, I wish it had been. Rather than the Borg kids, I'd preferred Sam have been written out and Seven take over her up bringing based on her established closeness with Naomi.
