Lady Grey returns in Fable II. You gain a quest called Love Hurts it is available after reaching Bloodstone. In the quest, the grave keeper of the Bowerstone Cemetery has an obsession with Lady Grey.
Once you have given him the body parts, he reanimates her with a spell that also casts a love spell on her. You can then choose to let the lonely grave keeper marry her, or marry her yourself. This reanimation is bisexual, so you can marry her even if you're a woman, though the actual Lady Grey from Fable was not bisexual at all, as it is the love spell that will make her as such. She is invulnerable to attack, but will divorce you should you try repeatedly. You can also sell her to slavers while doing the civilian displacement job.
It is advised to not turn in (or abstain from) the Love Hurts quest until after completion of the main storyline. This is due to a significant number of glitches associated with the quest reward, and effects on the playability of the end storyline.
Her personality changes from the original due to her resurrection. She is more capable of true love than the the previous Grey, on account of the nature of her revival, and seems to have lost her manipulative, power hungry edge. Her appearance has also changed quite a bit, though whether this was an oversight or just her resurrection is unknown. She also talks of having to resew herself, which proves the resurrection didn't fully restore her, but only revived her corpse.
