The child, listed here as 'Alien Child', is the same species as seen in the earlier season 6 episode 'Muse'. It is established in Muse that this is a pre-industrial, Bronze Age level culture. They have no space ships and nothing that the Borg would be interested in.
After Janeway attacks the Borg with the Bat leth it falls back with its legs closed then it's leg is bent up.
Janeway states that she is reinstating Tom to the rank of lieutenant; however, Tom never held the rank of lieutenant, he held the rank of lieutenant junior grade. As Janeway places a black pip on Tom's collar, that indicates his reinstatement as a lieutenant junior grade, not a full lieutenant.
During Voyager's decoy attack on the tactical cube, Harry reports that the ship has sustained a direct hit to the port nacelle and that the ship is venting plasma; however, in the next exterior view of the ship, no damage to the port nacelle is in evidence.
The Borg are obviously much more compassionate with Janeway, Tuvok, and Torres. In "First Contact" crew members from the Enterprise were seen with limbs and eyes removed and replaced with prosthetics, yet here, none of them have this happen.
If Klingons can imagine themselves in Unimatrix Zero with bat'leth and Seven can choose to imagine herself with different clothing and with or without Borg implants, why can't the drones simply imagine themselves with phasers or other weapons when they come in?
Seven is told that the Klingons are giving bat'leths to anyone that can use them in Unimatrix Zero. A Klingon wouldn't give up his own bat'leth, so either they are imagining extra weapons when they arrive or they are leaving them with others and the weapon does not disappear along with the rest of their equipment when they leave. Either way, it doesn't seem to work with how Unimatrix allows them to appear.
The Doctor congratulates Seven of Nine on her "first dream" yet she's had dreams before in Waking Moments (1998) and One (1998).
When Seven describes her dream, she tells the Doctor that she spoke to someone. In the dream, she did not say anything. When the person called her human name, she woke up.
