Everyday, since you took him in nine years ago, Lir looks at the sea thru his room's window. When he was younger he used to scare you by leaving the house by himself to go to the shore to stare at the waves.

You can't gauge the motive behind this behavior, whenever you've tried confronting Lir about his love for the sea he deflects the subject but you can tell something isn't right, something is making him sad and you don't know how to help.
