as much as verbal boyfriend confirmation would be nice for geo/cole, i genuinely don't actually think it's necessary for the relationship to be "canon" considering the standards for how most hetero relationships are portrayed in ninjago is as equally devoid of verbal confirmation or even like. consistent physical affection, with the exception of jaya. Like, pixane is barely more cuddly than most friends, and Kai canonically dropped the ball with Skylor by forgetting to call her for years. Quite frankly with the amount of physical affection present, calling each other family, and underlying romantic coding Geo and Cole have, I'd consider it the third most prominent romance in the series and I mean that pretty seriously.
I don't think we as a community bully Lloyd enough over the fact that he canonically sang a punk rock song about, of all things, not wanting to do the dishes. Never change, buddy
