After a mission or two from purgatory, Jack's recruitment mission, you get an email from "Billy" thanking Shepard for the accidental rescue, claiming he'll "carve Shepard's name into his next victim, not his own name" He then said that he'll kill Shepard the next time they meet. saying that Shepard took a shot at him, which is unrealistic. when Shepard shoots someone, he usually finishes the job😂 anyway, the email ends. So any thoughts or theories on this? i think it's the one that says "The screaming is nice, yeah..." at the start of the mission, or the prisoner who got beat up? or the other who wants to be bought "I wish i could go." nobody knows, but it's fun to theorise though!
