That's not how it works. [said simple and sad, having seen someone come through and then back out the mirror... it didn't work that way. They said they didn't remember anything when home, it only returned to them when they returned to the city. So, Soren doesn't have much faith in change for the better going through with his father.

Not to mention their further fall out in the last little while, due to what Soren told him. There's probably no recovering their relationship... but, maybe, Soren can help his dad through the others who care about him? Worth a shot.]

He has to stay here. If you really care about him, you're going to need to break that promise.
