Riley in season one sounds rather young. As expected from a fourteen year old boy. A little cracky or raspy, also expected from a fourteen year old boy.

Struggling to live up to expectations and constantly being put under pressure Riley easily cracks. Faltering. Being just a boy he searches for the love of others, just wishing to be enough for others. Growing severely attached to those he has around him.

His role requires at least some emotional range. Being a rather emotional person at times.
