I've been re-watching early Season 2. Bo's attempts to win back Dyson remind me of my equally unsuccessful attempts to persuade my friends to watch Lost Girl.
"I've gotten as far as cleavage."
"Honey, that's further than some of us ever get."
Actually, now that I think about it, what's the deal with Bo never lifting a finger to actually get Dyson back?! I mean, it's not like it was a big secret what happened to him. Dyson told her what the Norn did. But it took Kenzi to think of the chainsaw option while Bo spent most of the season moping and subconsciously blaming Dyson. But, I suppose this is like Angel's gypsy curse on Buffy the Vampire Slayer.
It's not supposed to make literal sense. It's just a metaphor for the guy that randomly doesn't like you anymore.
