I will protect Lucas with my life. I don't know how there's so much content already! I'm absolutely blown away by how put together everything is. The grammar usage is great and so is the writing, so this error stood out to me. Because there are multiple subjects the dialogue should be:
"Aren't Travis and Conner bi?"
*Is* is used for a singular subject, while *are* is for multiple subjects. TBH I only learned a lot of the more intricate English/Grammar stuff recently myself and now I'm addicted 😅. Anyway, keep up the good stuff! You've got another patreon coming your way for sure.
