Yeah maybe since he's with Flame Princess now , then maybe he won't really worry about PB having a suitor. Maybe he's finally over her cause he can focus on another girl now.
Yeah I agree about Brocko , he doesn't seem like a good character to me. From looking at the preview it looks he's gonna get into PB's way too much of her annoyance. He could get really upset about her ignoring him and cause trouble which will lead Finn and Jake to save her. Though we'll see when the episode airs.
