From the file Micah pulled for Tracy, it says both their DOB as 1974. I remember back in season 1, when Niki was at Jessica's grave that her year of birth was 1976. I always assumed Jessica was either a twin sister or an older one, protecting her younger sister. Jessica was the YOUNGER sister? So if she wasn't a twin, why did she look EXACTLY like Niki when she saw her in her reflection?

Two years for adults isn't too much. Since it seems that Nikki, Barbara, Jessica, and Tracy are all clones, it wouldn't be surprising that Jessica, even 2 years younger, would look like Nikki.

True dat. in that respect, then its safe to say that Jessica's the one with Dimensional Entrapment. After being beaten by Hal so many times, she just jumped inside Niki's body.

To be fair, Gina looked EXACTLY like Niki too. I think Niki was just seeing other people in her reflection.

(I, too, thought Niki and Jessica were twins initially.)

Wasn't it established that Gina was just a MPD and not another twin/clone? Jessica was actually a person before becoming a MP, so shouldn't she look exactly like Jessica used to look like? If my sister, who is two years younger than me looked EXACTLY like me, it would be a bit suspicious, no?

But the only Jessica we've ever really seen was part of Niki's MPD. I know: tattoo, talking to each other and Matt hearing - yes, I don't like the MPD either. But apparently that's what she was. Niki's mind created another persona and called her Jessica after her dead sister.

Yeah yeah, fine, I'll accept that explanation. I still think that if my mind created a MPD after my dead sister, it would look to ME like my dead sister and not like myself. Unless I'm a narcissust.

Agreed. But I don't think the writers created Niki/Jessica with MPD in mind to start with. That seemed a lame and obvious-yet-not-quite-right explanation.

Maybe I was hearing things when I watched the episode, but didn't the doctor say that he "made" her or something?

yep when tracy went "doyou know me?" he goes "know you"? i created you"
