A Nice Day for a Right Wedding

 is an unmarked Fallout 3 quest.

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.


 * Giving Angela the Ant Queen Pheromones and waiting a few days will result in Diego 'seducing' Angela, and 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 excommunicate 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

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. 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.

It is also possible to witness the "seduction" of Angela. The following conversation has been observed as the couple return to the Mid-ship deck around 10:30:


 * ''The second exchange happens randomly as "chatter" between the two beforehand as well, and if overheard adds the "Angela and Diego" note into your Pip Boy

This seems to be the culmination of their affair, as Angela will eventually go to bed and Diego will, after waiting for hours outside her room, go for his walk on the flight deck. After his walk, he dines with Father Clifford at the Weatherly, where they both acknowledge the affair and Diego's subsequent resignation from the church.

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

Bugs
As this quest doesn't appear to have any long term effects other than a few dialog choices updating to take the marriage into account, a bug that prevents this quest from completing is not a very serious issue.


 * A bug reported in PC, PS3 and Xbox 360, results in the wedding never finishing. Ordinarily, the wedding starts with Angela walking down the aisle, followed by an exchange of vows. Instead, people just sit around in the chapel whistling while the couple stands next to the father, silent. The wedding is never completed, there is no karma boost, and every day at three another attempt seems to be made, ending in failure. The only known solution seems to be reloading to an early enough save.


 * In the PC and PS3 versions of the game as has been witnessed, the wedding goes normally at 3 o'clock and you gain the karma boost but Diego never shows up! This has happened to several people, however, after one player left the Church, he discovered Deigo stuck in a running position behind the motorbike by the entrance to the Science Labs.


 * In the Xbox 360 version it has been seen that the wedding never takes place. Everyone shows up including the couple, but the wedding never starts. After 3 PM the crowd just leaves. This happens everyday after 3 PM. No fix is currently known.

kill resurrect disable enable This will cause him to begin the wedding speech, allowing the script to continue. It is advisable to do so at 3PM at a given day, so the other NPCs will be present.
 * It is possible to reset the wedding if it gets stuck (on the PC only) by resetting Father Clifford. To do so, open the console with ~ and click Father Clifford to select him -- his name and Reference ID should appear on the top of the screen. Then use the commands in order:


 * During this bug (after 3 and still no wedding started) Angela will disappear from the aisle while everyone including Diego is still at the altar. To fix this, locate Angela outside the church in the hallway, talk to her (doesn't matter what you ask her) and she may then return to the wedding ceremony. If not, then skip time ahead by an hour and Angela may now be now at the altar with Diego and the ceremony started.


 * Though not technically a bug, since many NPCs are all located in the same area for the wedding, as soon as the wedding ends and everyone stands up, they all immediately start conversing with one another, resulting in multiple conversations all occurring at once, many with the same dialogue (observed in the PC version and the Xbox 360 version).


 * Diego spends late nights wandering Rivet City's flight deck, and has an unfortunate tendency to wander off the northern end of the flight deck and kill himself on the walkway below. Even though Diego may die, this won't prevent the wedding -- Angela will happily stand at the altar and say her vows alone.


 * The bug can be encountered by waiting in Chapel for the wedding to start. Wait in the Marketplace and then enter the mid-section and head to the chapel near the wedding time.  Everyone should be in their right place.


 * Killing Angela or Diego after convincing them to marry, but before the wedding ceremony, causes entering the Rivet City Marketplace to freeze your game on the Xbox 360.


 * In PC version of the game, when you take a seat in the church prior to the other characters arriving, a NPC can still sit in the same seat as you. This happened to me when I sat on the right side of the green bench at the front where Gary Staley sits.


 * The NPCs may enter the church and once everyone is in they stand up and leave. Then if you talk to people they say they've already gotten married, resulting in no karma boost

Trivia
The quest title is an obvious reference to the chorus line, "It's a nice day for a White Wedding" in the song "White Wedding" by Billy Idol.

Also if you kill Diego and get the ant queen pheromone to Angela within 34 minutes(in game time) she will have the wedding anyways and stand there alone.
