I am not referring to getting her pregnant. I am specifically referring to making her an ally. Her being pregnant still gives the footnote I am speaking of, at least with the routes i have found so far.
On an aside...
I think you can get her pregnant a couple of ways in the first week...
1) for sure is you can met Jill and Lydia when leaving the library and use a light on them obviously finishing inside Jill
2) I think some of the classroom light scenes give an option to get jill pregnant.
The thing is i have never seen a Jill scene that you specifically pick to target jill. It appears that Jill is an ancillary character to multiple scenes but not a character where you can target her specifically. [At least on the paths I have taken previously with the game.]
theres a few in history class there a greed spell to which you can target jill spefically
in one of the store scenes you can greed again the one with pay 1000 for orgy with all three ladies if you scroll down you can target jill specifically
so you can pay 500 for jill 500 for lydia 500 for miss hill
in the park scene i was mentioning if you cast invasibility you can target jill specifically
and again in history class the a brown bimbo jill option those are the 4 off the top of my head.
if theres more somone please mention them or correct me
