Also a necrocommentor here. I acknowledge the themetic importance of Leo's route, so no arguments there; however, that does not entail our wishful desire for our boys to reunite are any less or insignificant. If anything, heartfelt and human.
Here is my reality: I once knew an emo greaser kid in middle school who despised others, including me, just to look cool and edgey. You know what happened? I changed him. How? By simply being his friend. To this day, we are brothers for life. Scary, right?
I like Arashi's optimism and hopefulness, but it takes two to tango of course. Leo said he wants to change for Chase, GREAT! The challenge is is that Chase might not (depending on the route), great...we can point out literary irony when Chase chose to return to Echo in the very beginning despite moving on and knowing better. Conversely, Leo has forgiven, though not forgotten, their past despite wearing the anchor bracelet symbolizing otherwise.
