Hook telling Belle that Rumple loved her and her getting all teary-eyed…
Those were probably the only kind words she’s heard regarding her marriage to Rumple since she banished him.
Everyone else is probably so filled with anger or hatred for him. And Belle has to walk around the town with people side-eyeing her for marrying the Dark One, talking behind her back, all the “hate to say I told you so…” looks.
And probably the only support she’s received about what happened came from Rumple’s nemesis. Because Hook hates Rumple but feels for Belle - and also knows that a villain with a dark heart is still capable of love.
He’s simultaneously plotting to kill Rumple - but is also his wingman.
Belle badly needed some comfort. I just really loved that scene.
