My seven knowledge is more than a little foggy but I'd always assumed that Lucrecia was impregnated (Either through artifical insemination or though...the usual method) by Hojo stictly as an assistant/test subject. I'd assumed that this was with her consent.

As the the status of her relationship with Vincent, I assumed they were not-quite-a-couple. (You know when you see a guy and a chick on TV and you KNOW they'll be together by the end of the season, they're just not right now? Like that). After all if it was concentual and Lucrecia HAD been in a relationship with Vincent I'm sure Vincent would have been consulted, said no, and the game would have never happened.

This is all assuming it's with consent. It's a very different story if it wasn't.

Um, as absolutely disgusting as this sounds, Lucrecia actually got it on with Hojo. There's a cut scene in DoC where Hojo says "so you chose me did you?" and Lucrecia falls into his arms and says "yesss, doctor", which was completely euuuuuww but it's true. After Vincent's father died I think Lucrecia lost any feelings she had for Vincent out of guilt, and went to Hojo instead. Therefore the unborn Sephiroth is a result of that.

Vincent was deifinitely in love with her, but they were never a couple, which obviously affects Vincent as a start. He says he failed to protect her because she allowed Hojo to talk her into experimenting on their unborn child in the name of science. Vincent was unable to stop them, and he blamed himself for it, calling it his sin. Of course it's not really his fault because Lucrecia had made up her mind, but I get the feeling he still thinks he could have prevented it somehow. He tried to tell Hojo that it was wrong, and ended up getting shot.

Lucrecia is a scientist and so is Hojo. As an experiment to inject Jenova cells directly into womb to create a baby with what was believed to be the powers of the Ancients, Lucrecia agreed to bang Hojo silly in the name of science. To be honest she could have just settled with me, I wouldn't have minded. Vincent, being the emo that he is, developed strong feelings for her and didn't want her to go ahead with this project. Lucrecia did it anyways and Vincent blamed himself for not protecting her. So off he tots to have a row with Hojo which ends up with Vincent eating lead and geneticly alterd to be able to transform into a purple horned monster. Oh Hojo does like his experiments eh. Anyways around this time Lucrecia also discovers Chaos and the Protomateria. Being the selfish whore that she is, decideds to implant it into a pretty fucked up Vincent without telling him. Vincent is put into a sleep for his 'sins' because he's a gullible emo and hates himself. But to actually answer your question, no they were not a couple at all.

Oh boy, you HojoLucrecia haters are superficial. Why should it be always that only beatiful people get laid? Why can´t sweaty nerd like Hojo get a chick and leave emo hunk lonely?

I think it's less to do with appearance and more to do with the fact that in the game Hojo was shown as one of the biggest womanizing jerks in existance.

Who am I kidding, it's more likely just because Lucrecia can act as a fangirl surrogate and there are far more Vincent fangirls than Hojo ones.

Got it in a nutshell

Because, euuugh!!! It's not so much that he's a sweaty nerd, the guy is screwed up and self obsessed. "I'm a genius! I'm a genius!"

True, there would be no Sephy without Hojo and Lucrecia's relationship. And we do all feel very sorry for Vincent which makes him more appealing-and sexy

Lol
Well I think it's like this....Lucrecia and Hojo were actually a couple and Lucrecia did love Hojo...slightly, but not as much as she loved Vincent.
Lucrecia did agree to get the Jenova Cells injected into her in the name of science and Hojo, she did care for her baby you know.
Vincent developed feelings for her and was unable to stop her from going through with the experiment. Blaming himself for not being able to stop her well...he goes emo.
Lucrecia and Vincent could have been a couple but she also blamed her self for the death of Vincent's father. So...now she goes emo as well v.v;;

Hehehe makes a lot of sense. And they say Squall was the first FF emo
