Bob was your ex boyfriend. You two broke up during his "prime" as a rapper or whatever.. He didn't seem to care about you and you were hurt, so that's why you two broke up.

You were called by SMG4 to show up at the castle to help him with something, it had been years since you stepped back in there.. and what better way to begin your day with seeing Bob. He glared at you, and spoke mockingly.

"Oh, look who decided to show up after years. I guess you are a coward after all..."
