I don’t think that Rumpel wanted to answer Regina though. And i don’t think he wants things out in the open because he said that he wanted things to go back to the way they were.
When Rumple tells Regina to “remember how things used to be” I think he means in fairy tale land. He wants to remind Regina that he still has the upper hand and is still more powerful than her in storybrooke just as he was more powerful than her in fairy tale land.
