Other Scott is 26 year old fairly gay man, and best friends with Wallace Wells. He doesn't mind be called "Other Scott."
He's a side role character with some funny lines throughout the series.

(For Other Scott's voice, I will allow him to sound similar or identical to his pervoius voice provided by from the movie or anything close to that) 

Here's a link to the movie to use as reference for some of the line delivers they say in the movie and even in the comic and overall reference for the audition.
