This requires a speech skill of 20. Talk to 10 of Spades in Camp McCarren. You may need to find out about Corporal Betsy's trauma beforehand. Anyway, open a dialogue with him and select "I heard about what happened to Corporal Betsy" then "Tell me what happened." Your next options will be the speech check or "If you were unconscious, how could you have done anything?" Do the speech check, then the other option is the only one available except "Never mind." After you select the unconscious option, the speech check will be available again, but grayed. Regardless, keep pressing A and they'll alternate. Even though the check is gray, it still counts as a pass. NOTE: This does not glitch XP as well.
