I agree. As Sparks go, Klaus is one of the most sane we've seen (meaning, he has real, sane reasons for everything he does). I wonder how much of his maturity is simply due to age? I don't think we've seen a Spark older than him either.

Good point about Agatha's grandmother. That woman is the only reason Agatha is even partly sane. I wish we could get that story.
