Where in the galaxy is Keiko O’Brien?
I keep getting confused about when Keiko is on the station and when she’s away, and sometimes I get a plotbunny and then realise that she’s not even there at that time. When I sat down to look at it, I realised I have way too much knowledge about this, so here it is - all of Keiko’s known movements during Deep Space Nine. I’ve double-checked everything I remembered on Chakoteya and Memory Alpha. I can’t guarantee I haven’t missed something, but if I have, it’s on the level of going away for part of an episode.
I hope this is useful for fic-writing and other endeavours!
1x01 The Emissary
Keiko arrives to DS9 along with the Enterprise. She talks about taking Molly and going back to Earth, but then doesn’t.
1x01-2x202 Keiko is on DS9.
2x03 The Siege
Keiko and other civilians are evacuated from DS9, and are to the taken to the Korat system. However, the first shuttle with evacuees comes back at the end of the episode, so they may not even have made it to the Korat system before turning away.
2x04 Invasive Procedures
Everyone but a skeleton crew is evacuated due to a plasma storm. She is back on the station by the next episode.
2x22 The Wire
She is away at a hydroponics conference on Rigel Four for more than a week.
Two weeks after 3x03 The House of Quark
Keiko leaves for the expedition to the Janitza Mountains, taking Molly with her. Miles tells her in 3x03 that the expedition starts in two weeks. It’s unclear how big the gap between 3x03 and 3x04 is, as neither episode has a stardate, so it’s hard to say if she’s gone by 3x04. However, Miles does not appear in 3x04, so we could theorise that he’s helping her get everything ready and follow her down to Bajor (because you know Miles would fuss over that kind of thing).
3x10 Fascination
Keiko and Molly come to visit DS9 for the Gratitude Festival, staying for two days.
3x11-4x16 On Bajor. In Fascination she says she will be away two or three months longer. I lean towards this being longer than that. We know Keiko spends one night at DS9, at which point she gets pregnant. This could be the same time as Fascination, but I don’t think so, as they would have had to decide that they were going to try for a baby, and that is not something they talk about in Fascination (as at that point they almost break up). Furthermore, this must have been something that is planned ahead more. From events in s7, we know that Sisko takes a contraceptive shot once a month, and it seems possible or even likely that Miles is on something similar. That means that he has to go off it, and it also explains why he’s surprised she’s pregnant, because she says “I thought it’d take a couple of nights. To be honest, a lot more nights.” (That is partly just that he wants to have sex with his wife, but if he’s just stopped taking contraceptives, that might explain that further.) On top of all this, I have calculated (from when I wrote my Keiko/Kira fic) that Keiko is eight or nine weeks pregnant in Accession. (This was based on chronological markers within the episodes of s4 and counting backwards from Body Parts. Kira is pregnant for five months, so it’d be logical that Keiko is four months gone in Body Parts, and stuff in the episodes between Accession and Body Parts makes a two-month gap likely.)
4x17 Accession
The expedition having ended, Keiko is back on the station.
4x25 Body Parts
Goes to Torad V in the gamma quadrant for three days together with Bashir and Kira.
5x05 The Assignment
Goes on an expedition to the Five Caves for five days. (Comes back possessed by a pah-wraith - man, she needs to stop going to places with ‘five’ in their name…)
Two days before 5x26 Call to Arms
Leaves the station to live on Earth together with Molly as the war is heating up.
5x26-6x24 On Earth. Memory Alpha says she is gone almost a year, and often, a series is about a year, but in 6x16 Miles mentions that she has been gone for six months, so it might be shorter. There is no mention that I can find that she was away a full year.
Before 6x24 Time’s Orphan
Comes back to DS9. Considering the conversations in the beginning of this episode, it sounds like they have gotten back the day before or so.
7x26 What You Leave Behind
Moves to Earth with her family.
