Yeah, I would personally prefer to simply require them to come to terms with something that's physically or spiritually holding them back. Like for Henry, it could be his and Gaomon's relationship. Gaomon needs to realize that the two care about each other and want to protect each other. It's not just a one-sided deal. Henry needs to realize that Gaomon sacrifices a lot to keep him safe...and he needs to come to terms with how difficult he's making Gaomon's life, even if Gaomon doesn't admit it.
