I don’t know. If i had Sami and Lucas for parents, I might be glum too. Disfunctional family comes to mind and he is a moody teenager for sure, just what did he have to be happy about? I always felt he portrayed him as smart and compassionate, just not ready to expose his feelings, like is mom does. I would want hide if she were my mom.
These are just mythoughts. I’ve given up trying to figure out how or why they want the actors to portray their characters as they do, since they write such strange story lines for them.
