I thought Hook look a little less into it in that scene too @nevermore
I was reading that link you posted and it mentioned a certain triangle in Lost. We often compare CS to Spike and Buffy and how unhealthy that was (even though that was the intent of the show), but reading that link reminded me of another couple that perhaps represent CS more accurately: Sawyer and Kate from Lost which coincidentally is the same show that A&E worked on before OUAT.
