Yup. The show “got” their LGBT ‘ship. The writers can check mark that off and move on.
Besides, even if Robin and Hook both stayed dead for SQ to happen, would that honestly be that much better of a reason to kill Robin off? Both OQers and CSers would call foul that they killed both characters for a ship, and we’d never hear the end of it. Either option would have led to disastrous results.
