Oh, Brother

Oh, Brother is a Stranger mission in Red Dead Redemption 2. It is a three part quest that becomes available in Chapter 4, after completing "The Battle of Shady Belle".

Story[]

Proetus and Acrisius are two twins, who are competing over a woman named Helen. They are trying to prove their love and show manliness to Helen.

Walkthrough[]

“

Two brothers seeking adventure in the West, Acrisius and Proetus, have bottles shot off their heads to prove their bravery.

„

Proetus and his brother Acrisius are seen arguing outside of a store in Valentine. Proetus asks the player to help them prove their courage to Helen. He suggests the player shoots bottles off the top of his and Acrisius' heads, and the player has no choice but to accept.

They head to the back of the saloon and place a bottle atop their head, and the player successfully shoots the bottles. Then the brothers suggest they use smaller bottles, and proceed to put smaller ones on their heads. The player manages to shoot them off also.

After that, they then come up with the idea to perform the previous action but while standing on one leg. They do so and wobble about, but the player successfully destroys the bottles. The brothers will then leave with Helen.

In the second part, Acrisius and Proetus are found again in Valentine competing for Helen's affections, and will ask the player again to prove their manliness. To accomplish this, the player must punch both of them two times - first time in the face, second time - in the stomach. After taking punches, the brothers insist that the player should kick them both in the groin. Helen has had enough by this point and takes the brothers away.

In the mission's third and final chapter, Proetus and Acrisius are at Cumberland Falls, where they each climb into a barrel and ask the player to push them down a river and over the falls. The player and Helen ride down after them and find that they both miraculously survived the fall. The shaken brothers agree to stop antagonizing each other for the sake of a woman and depart to explore the West. Helen and the player then part ways.

Trivia[]

In "Oh, Brother I", if the player kills one of the twins, the other will say their name in shock as he and Helen look on in horror. The mission will then fail.
Unlike most stranger missions, when the first (or first and second) encounter is completed by Arthur and the arc is finished by John, there is no unique dialogue addressing John being a friend of Arthur's who passed. The twins will act as if they were already acquainted with John beforehand.
There appears to be a bug where, during "Oh, Brother II", Proetus and Acrisius's dialogue will emit from the wrong brother, while the correct brother's mouth moves.
If the player kills the twins before entering "Oh, Brother I", bystanders and lawmen will ignore the crime.
If "Oh, Brother I" is entered without any sidearm, the protagonist will freeze, leaving abandonment of the mission as the only option.
Mission "Oh, Brother II" can be failed, if one of brothers die. However, performing that is near impossible, as the player is locked out of their weapons.
In the game files there is a removed ped named CS_twingroupie_02, a unused female character that was part of the mission.^[1]
In Greek mythology, Acrisius and Proetus were brothers who quarreled even in their mother's womb. When their father (Abas) died, Acrisius expelled Proetus from his inheritance and became king of Argos. Proetus later returned, and Acrisius was compelled to share his kingdom with his brother by giving Tiryns to him, while he retained Argos for himself. Acrisius was the grandfather of Perseus, who would later kill him.
If the player uses trainers on PC to kill Helen in "Oh Brother I", the twins will exclaim her name as she dies, and a hidden animation triggers where Proetus tries to attack the player but Acrisius holds him back, and the mission fails shortly after.
