Wallace Wells is Scott's cool gay roomate, they met in college. While he jokingly shows interest in Scott on several occasions, Wallace is almost always seen to be in a relationship with many other male characters throughout the series. He is snarky and sarcastic but also has an easy going personality to him. He will also tell you things you need to hear even if you dont like it. He does the best he can to try and help Scott train and prepare for his fights. Even if he usually uses "training" as an excuse to torture him.

(For Wallace's voice, I will allow him to sound similar or identical to her pervoius voice provided by Kirean Culkin 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.
