Miria

Miria is a joinable NPC in Fallout 2.

Miria is the daughter of the slaughterhouse owner Grisham in Modoc. You can "recruit" her into your party by sleeping with her. After you've done the deed, Grisham will barge in and confront you. If you're male, you can try to talk your way out by telling him it was a "medical examination". If that doesn't work, you have only two options left: run for the hills or a shotgun marriage. You can also marry her if you're female.

If you run, the town of Modoc will turn hostile, so make sure you're finished with the area before you do.

Miria is absolutely worthless. She cannot level up and her skills are horrid. However, you can pimp her out to trappers or sell her off into slavery. If you leave Miria anywhere, you can go back to Modoc and tell Grisham you think she's dead. He'll have a heart attack on the spot.

Miria's alter ego is Davin, her brother who you can be married to instead.
