In 2103, Sheena is the tactician of the Crater War Party and plans out their operations against the Brotherhood under the orders of Meg Groberg. Sheena is one of the three raiders that inhabit the Crater war room along with Burke and Pierce. She has known the two from back when she helped an imprisoned Pierce escape with Burke. When Marcia Leone joins the gang, the young women become fast friends.
Sheena is rather misanthropic, saying she does not give two craps about humanity, saying the species has done nothing but abuse and betray each other, also pointing out their world has been destroyed by nuclear warfare. She mentions she will only look out for her and her own, saying the rest do not matter.
Property Rights: After the confrontation with Pierce in the makeshift vault, the Vault Dweller meets Sheena when Pierce refuses to cooperate. Sheena strikes a deal to trade intel for intel; she will reveal the source of where the Raiders found their weapons if the Vault Dweller returns her holotape once it has been downloaded with Brotherhood information. The Dweller is free to refuse.
If one calls Burke a freak in conversation with them, Sheena will come to their defense, though Burke will remark that they are not surprised by such remarks anymore.
Telling Sheena she can rot in prison will result in a "fuck you" from her.
If Marcia is convinced back to go back to Fort Atlas, Sheena will be extremely disappointed and tries to remind Marcia that the Brotherhood of Steel are their enemies. Marcia tells her that even though they may not be together, she will always view Sheena as her family and that she will never forget the impact she and the rest of of the group had in her life.
"What don't I do around here? Pierce has a way with words, but if he was in charge of our combat operations we'd all be dead. Everyone else is too busy writing war cries or painting skulls on their armor to make a plan. I don't mind it, though. Doing things myself means that other people can't mess it up."
"I don't give two craps about humanity. As a species, we've done nothing but abuse and betray each other. And beyond that, look at what we've done to this Earth. So I look out for me and my own. The rest don't matter."
↑Burke: "My employer was holding Pierce prisoner. I was his guard. Even in that situation, Pierce treated me like a person. Not as a tool. He saw me. When Sheena arrived, we all escaped together. The rest is history." (Burke's dialogue)
↑Sheena: "I don't give two craps about humanity. As a species, we've done nothing but abuse and betray each other. And beyond that, look at what we've done to this Earth. So I look out for me and my own. The rest don't matter." (Sheena's dialogue)
