A Nice Day for a Right Wedding

 is an unmarked Fallout 3 quest.

Background
Angela Staley is in love with Diego, however Diego is an acolyte and cannot return her affection. After chatting with Angela, the Lone Wanderer learns that she wants some Ant Queen Pheromones, so that she can seduce Diego. The player can also ship the couple by lying to the priest, or wreck the couple by convincing Diego to abandon the girl in favor of the church.

Walkthrough

 * Giving Angela the Ant Queen Pheromones and waiting a few days will result in Angela 'seducing' Diego, and him deciding the honorable thing to do is to leave the church and marry her. The pheromones can either be acquired from Cindy Cantelli in Rivet City Marketplace's A Quick Fix or by killing an Ant Queen, such as the one in the quest Those!.
 * If you tell the Priest of the Church that Diego is sleeping with Angela (a lie), he will expell Diego from the church and the two lovers will get married.
 * If you press Diego about the situation, he will tell Angela not to speak to him again, and the quest will end
 * If you kill Diego, Angela will talk as though he's there. (ps3 confirmed)

It is possible to watch the marriage. After providing Angela with the Ant pheromone or lying to the father, speak to Angela after a few days. She says to get a seat at the church by 3pm the next day. You may also speak to Diego to find out about the wedding location and time. Alternatively, Rivet City's resident gossip maven Vera Weatherly can give you this information as well. Angela's father can also inform you by asking him if Angela is still mooning over Diego, this can also be asked after the wedding, to which he replies you're behind times, and that they're married. Go there at 3 and they perform the ceremony. Most of the citizens of Rivet city attend and at the end of the ceremony you gain Karma. To start the wedding simply take a seat and the church fills up with residents. This may take some time.

If you kill Father Clifford before the wedding (while he is in the church "preparing" for the ceremony) Angela and Diego will never show up.

It should be noted that, after a successful wedding, Angela and Diego get their own room. Leave the Church, turn right and open the first room left. Before the wedding the room is a bad place, after the wedding there is a little furniture in the room together with a double-bed.

It is also possible to witness Angela's "seduction" of Diego. The following conversation seems to take place the first time the couple meet after giving her the pheromones -- it has been observed both on the bench near the baseball diamond on the flight deck (Diego goes up there around 9:00pm, though Angela may not always join him) and as the couple return to the Mid-ship deck around 10:30.


 * The second two exchanges happen randomly as "chatter" between the two beforehand as well, and if overheard add the "Angela and Diego" note into your Pip Boy. Also, sometimes (at least after giving Angela the pheromones), Diego responds to her "do you think I'm sexy" question by objecting that "we're not alone... maybe later today."

This seems to be the culmination of their affair, as after this they each go to bed in their own rooms (or alternately, Angela will eventually go to bed and Diego will, after waiting for hours outside her room, go for his morning walk on the flight deck). Either way, in next morning he breakfasts with Father Clifford at the Weatherly, where he apparently confesses the affair and gives the Father his resignation from the church. (They normally arrive at breakfast around 7:00am, and if you talk to any of the relevant characters after 7:00 they will tell you about the wedding -- even Angela, if you wake her up in her bedroom!)

Another scene between Angela and Diego takes place the night before the wedding, on a bench near the baseball diamond on the flight deck, at about 9:25PM.

If you are playing as an evil or very evil character (or if you have either a grudge against Rivet City, the couple's marriage, or just want a severe change of karma), this wedding is the easiest time in which to kill the inhabitants of Rivet City. Although they can all be killed within the church, some players have found it fashionable to set mines periodically along the hall outside (to finish off fleeing NPCs) and then open fire on the guests and participants. Long live the happy couple.

Bugs

 * Diego might not appear at the wedding but it will continue on as if he were there shortly after Father Clifford asks him if he takes Angela as his wife.. (PS3, PC, and Xbox360 Confirmed)


 * The marriage might be bugged occasionally causing Angela, Diego, and Father Clifford to be stuck in the church and will not move unless one of them is killed. (PS3, XBox360 & PC confirmed)


 * Also as everyone sits in the church, if you talk to Angela sometimes she will pull out a pencil and paper to take your order at Gary's. She then starts her normal walk protocol in the market.


 * Similar to the above bug, all people will be in attendance, but nothing will happen. No dialogue takes place and the wedding is not completed. At 6, when the wedding was supposed to be over, everybody gets up and acts as if nothing happened. They resume their normal dialogue as if they were meeting eachother in the hall. The next day the same thing happens. Everybody gathers but the wedding is not completed properly, and it repeats every day to no avail. Disabling then enabling Father Clifford using the console commands will cause Father Clifford to begin the wedding dialogue (PC).


 * Sometimes if you talk to Angela before starting the unmarked quest,she will continue to talk about the ant pheromones but even if you have them she will not take them. (PC confirmed)


 * Sometimes when choosing the path of lying to Father Clifford about Diego, both lovers will talk about getting married but never invite you to the actual ceremony, which never takes place. (PC confirmed, 360)


 * When encountering a bug preventing Father Clifford from starting the ceremony, using the console, targeting him, and typing "Say RCPriest" will correct the problem. Furthermore, if the marriage invitation never occurs, this can also be a fix of sorts; though you won't see the wedding, it'll allow the game to believe it has occurred, correcting the dialogs of the two lovers afterwards, and enabling anything relying on the marriage as trigger to happen normally. (PC only)


 * If a bug happens when everybody at the wedding is not doing anything but sitting down or standing, one way to get rid of it is to punch one of the children (not shoot) and then start to run out of Rivet City to somewhere else but there. After a few days past by if you go visit everything will be back to normal with Angela and Diego married. (PS3 Confirmed)

Behind the scenes

 * The title of this quest is a reference to the song "White Wedding" by Billy Idol.
