A Nice Day for a Right Wedding

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 unite the couple by lying to the priest, or wreck the couple by convincing Diego to abandon the girl in favor of the church.

Walkthrough

 * The player has three options at the start of the quest:
 * 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 Father Clifford that Diego is sleeping with Angela (a lie), he will expel Diego from the church, but there will not be a ceremony because of the lovers' sin.
 * After providing Angela with the ant pheromones or lying to Clifford, speak to Angela, Diego, Vera Weatherly, or Gary Staley after a few days. They will tell you that the wedding will take place in the church at 3 pm.
 * Go there at 3 and they perform the ceremony. To start the wedding simply take a seat and the church will fill up with many of Rivet City's named non-player characters. This may take some time.
 * It has been noted that this event can have a delayed trigger, making it happen strictly during Fridays, if it doesn't work to wait until 3 PM the day after they inform you about the wedding, try speeding up your clock until Friday comes, then access to the church at 3 PM.
 * After a successful wedding, you will receive positive karma and Angela and Diego will proceed to their own room. The room is down the hall from the church, the first room on the left. Before the wedding the room is empty, after the wedding there is a little furniture in the room together with a double-bed.

Reward

 * Positive karma (+100)

Bugs
Another solution is to punch one of the children and run to a different room and return immediately. NOTE You must enter a room that must be loaded, like the market.
 * 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.
 * 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.
 * 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.
 * 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.
 * 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 each other 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.
 * 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.
 * 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.
 * If you kill Diego, Angela will talk as though he's there.
 * Occasionally Father Clifford will go to the front end of the church and stand in place at 3:00, but no one will show up. Not Angela, Diego, nor any guests. After several hours, Father Clifford just leaves.

Behind the scenes

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