Hammer comments twice during The Ritual quest about how Sparrow doesn't talk much. So it's not just a skip over like Fable (TLC/Anniversary) in which the characters act like you talk.
Sparrow just doesn't.
So I think of them as a mute. Perhaps from a trauma in their childhood (like Rose's death) or a disability. Which would explain why they're so expressive.
I know that it's for gameplay reasons, but the fact that Hammer mentions it gets me.
Mute Sparrow!!
