“I don’t think that Hook giving up his ship was the biggest sacrifice made in 3b. I understand that a ship is the symbol of who he was, and his home for hundreds of years. However, I think that Charming sacrificing his heart is way more of a sacrifice than giving up a ship. When Hook gave up his ship, he still had potential to find Emma and be happy. Charming understood the fact that he would never see Snow, Emma, or his unborn child ever again.”
Or Neal giving up his life, is one big sacrifice.. Dead is dead, no turning back..
Same with Rumple, he gave up his life as well.. One of the things he feared the most.. Regina, giving up her happy ending for the sake of Henry.. The one thing she fought her whole life for..
