Since Keiko turned down doing an arboretum in "The House Of Quark", where did the O'Briens get the tree and grass for the cargo bay? Did they make a special trip to Bajor or back to the picnic planet for them?
Dax says that Alexander was 4 years old when he moved onto the Enterprise with Worf, despite the fact that he was only conceived 2 seasons previous. A possible explanation is that Dax was referring to Klingon years, which would mean Kronos circles its sun once every six Terran months.
Worf: (shaking a rattle at Yoshi as Julian and Miles come in) Gong, gong, gong.
Bashir: Gong, gong, gong?
Worf: I was instructing your son in Hech Dup.
Bashir: Hech Dup?
Worf: It is a Klingon exercise designed to teach children hand-eye coordination so they will grow to be warriors.
Bashir: Oh, I get it, it's like the rattle's baby's first bat'leth, kind of thing.
Jadzia: (volunteering to take over with Yoshi, who won't sleep) Worf, you're exhausted! Get some sleep.
Worf: No. I am a Klingon warrior and a Starfleet officer. I have piloted starships through Dominion minefields, I have stood in battle against Kelvins twice my size! I courted and won the magnificent Jadzia Dax. If I can do these things, I can make this child sleep.
Jadzia: (incredulous) Talk about losing perspective!
O'Brien: We pulled her out ten years too late.
Bashir: It's a miracle you managed to get her back at all, Miles.
Keiko: Maybe if you tried again, you could pull her out when she was still a little girl.
Bashir: If you do that, there'll be no one to grow up and become this Molly. You'll be erasing her existence.
O'Brien: Yes, but we'd have our Molly back!
Keiko: Miles, this is our Molly. Just because we missed the last ten years of her life doesn't give us the right to take those ten years away from her.
Cirroc Lofton (Jake Sisko) does not appear in this episode.
Chester, the cat from "Honor Among Thieves", can be seen in the O'Briens' quarters in this episode.
This episode was originally conceived for The Next Generation. The main focus would have been Alexander who would have grown older; it was also considered the possibility that Alexander would not have been restored to his childhood at the end.
Children Of Time
This episode is similar in some ways to the 5th season episode "Children Of Time", and has, essentially, much the same answer for the question of 'time developments', the paradox of what do you do if you change events and alter the results that produced people and lives that depended on the event. In this one, they pluck an 18 year Molly from 10 years after she was accidentally deposited into an Eden-like place. Instead of continuing to fish for the 8 year, they elect to attempt to bring the now somewhat feral child back to civilization, arguing, basically, that the 18 year has as much right to exist as the 8 year they would be bringing back (thus destroying the 18 year variant who would never have developed). In the end, the feral Molly, who is failing to adapt, is being returned to the place she came from. An anomaly in the portal sends the 18 year back, instead, to shortly after she arrived, and she winds up face to face with her 8 year self. She sends the 8 year back through the portal she came from, and fades from existence, her history eradicated.
