This whole thing has just been really fucking stupid on pretty much all levels.
You do realize that the phrase “kawaii yaois”, is intended to be ironic, right?
Horuss is just as strong as Equius, he has a set of steam powered destrengthening gloves.
Given what we know of Dirk, I feel I can safely say that Bro’s relationship with Dave was probably pretty similar to Vriska’s relationship with Tavros, but done right, and without the sexual tension.
So basically, Bro almost certainly pushed Dave as hard as he could, and tried to instill in him a sense of absolute dedication toward what he believed in, while still understanding what was possible and what wasn’t, and when to let up.
