Lydia Montenegro

Lydia Montenegro is a resident of Tenpenny Tower

Quests
Tenpenny Tower: She is one of several bigoted residents that the Lone Wanderer must convince to change her views if they choose to advocate for Roy Phillips and the rest of the ghouls' admission into Tenpenny Tower.

Effects of player's actions
She will leave the tower if her safe in Boutique le Chic is looted, claiming it's not safe despite all the guards. If her safe is looted before she is spoken to, which triggers her to leave and wander aimlessly around the wasteland, she will only come back if Roy and his gang are killed.

If she is convinced to leave, or simply killed, house upgrades will no longer be available to buy. If this happens, the only other option is to let the ghouls invade the tower. After the invasion, Michael Masters will take over the shop, and his shop will sell the house upgrades.

Appearances
Lydia Montenegro appears only in Fallout 3.

Bugs
If she decides to leave Tenpenny Tower, she supposedly heads out to Megaton and can be found outside the main gate causing tremendous graphics lag for some reason. Scaring her away or killing her instantly removes her effect on performance. Note that if you kill her while she is at Megaton, all of the guards outside Tenpenny Tower will become hostile, regardless of whether the killing is witnessed.
