Oh lord… I was watching Smart guy again because 90’s, and I came across the episode Gotta Dance. And I was just like…. Gus? Is that you teaching TJ how to tap dance? AND IT TOTALLY WAS.
So new head cannon: Gus obviously took some time off before college to teach tapdance in DC, he maybe even seriously considered it as a career path before deciding on pharmaceuticals and going to Pamona. Shawn has never been informed of this for obvious reasons.
THIS IS WHAT HAPPENED AND NO FACTS OR LOGIC ANYONE PRESENTS ME WITH WILL CONVINCE ME OTHERWISE. It’s too glorious an option to ignore.
