B E A R S (The Berenstain Bears '85 Abridged)
for Brother Bear
Brother plays a more genuine voice of reason than Sister, though sometimes not by much. While Sister gives snide remarks or complains about questionable or non-existent logic in a situation, Brother can be one to offer perspective from a more positive, curious or logical outlook. Sometimes, because of their clashing ideals and personalities, Brother could even play a Silent Bob-type in a situation due to Sister simply not wanting to hear it.
Voice: A more youthful teen voice, akin to a 14-year-old boy.
(curious) Papa, why do you want to catch Jake so bad? He's just a catfish.
(neutral, acting as a voice of reason) I'd hate to spoil the fun, but how is this keeping the lake clean?
(playing hide-and-seek, calling out to Sister) OK, nothing's going to stop me; not even your face!
Your take is the exact voice I was thinking of; something young, but not a flat-out child. Good job, and thanks for auditioning!
