After Amy's rather bruising sexual interface with Rufus, she asked one question before she left.
"Where did all that anger come from, Rufus?"
Rufus wouldn't normally have given an answer, but in his post-coital state he was putty in Amy's expert hands. She was very good. Unfazed by her ordeal, she nuzzled close, while out of him spilled intimate details about his relationship with his parents, particularly his abusive father. Mac2 across the room couldn't stop his outpouring.
"I'm glad the bastard's dead. Should've done it sooner!" And then, "Whoever killed him that is."
Amy now had her story.
