Jaheira Romance Walkthrough (MAJOR spoilers) ...

The locket is actually incidental, and not necessary for the progression of the romance.

You've completed all the Xar/Montaron quests? Also, what's the values of your romance variables? You can check them with Shadowkeeper.... Your JAHEIRAROMANCEACTIVE value should be 1, and you can set your JAHEIRAROMANCE value to 1 as well to get the next dialog.

Uhhh yes i did the quest xzar asked me to do...although i am not sure if i did it all. I grabbed the bird in the cage and returned it to xzar. Xzar then turned it back into a human, it was a harper (i forget the actual name but it wasnt montaron) and it killed xzar on the spot...and thats all i've done with that quest.
My variables are as follows:
JAHERIACURSED:10
JAHERIAMATCH:1
JAHERIARELEASED:1
JAHERIAROMANCE:434194
JAHERIAROMANCEACTIVE:1
JAHERIAROMANCE:1

Do you really have two "JAHEIRAROMANCE" variables?

Weird...Im not sure what to make of this, but i suppose i read the variables wrong. These are the variables as follows:
JAHEIRACURSED:10
JAHEIRAMATCH:1
JAHEIRARELEASED:1
JAHEIRAROMANCE:434194
JAHEIRAROMANCEACTIVE:1
JAHERIAROMANCE:1
Forgive me in the last post i typed jaheira's name as jaheria for all the variables. That is incorrect as i can now see.
Notice the last variable is spelled the way i thought her name was originally spelled, in other words, its spelled wrong. I wonder if that means anything.
And yes I do have 2 variables that are nearly the same but not quite :/ Now im plum confused.
Perhaps i should...delete the last one?

Ah forgive me for double posting but i have dissected, and solved my problem
I appreciate any further assistance that would've been given
The problem lay within the last variable, for some odd reason that wasnt supposed to be there, so i removed it. And I got another dialogue
Thank you all kindly
