Ok so i searched the forums and couldnt find any other references to this so here we go.

End of BG2 if you dont romance Jaheira:
The events of the Bhaalspawn saga affected Jaheira deeply. It was her duty to protect the greater balance of things, but in the years to come, she found an increased portion of that fight occurring within her own mind. Witness to great change while in Charname's company, she had become acutely aware of how fleeting life was and how the loss of those she held dear ate away at her thoughts. In time, she would be known as a tireless champion of balance, one that sometimes acted in concert with the Harpers and sometimes did not. Always, however, she remained distant and guarded, never staying long in any one place. Jaheira would cross the realms thrice over, but she never did return to Tethyr or the Sword Coast.

Minsc ending leaves it open enough for what happened to him canonically, but Jaheria...
