I always wondered if Tirek's grandmother has passed away and there was a deeper meaning behind the comedic moment that happened in Frenemies. It is one of the funniest scenes in the episode, with Cozy and Tirek arguing. LOL But still, what if there was a deeper meaning. What if Tirek's grandmother really is gone and that Tirek deeply misses her. I mean, that will explain why she is the only family member he deeply loves and misses her very much. His grandmother must have been the one who gave him comfort and love during his childhood. Also, I named Tirek's grandmother Thalina, the former Queen of the Kingdom that Tirek lived in his early life. :) But yeah. Here is a screencap of Tirek from The Summer Sun Setback with a caption.
