Lol. I just took a look. Pretty hilarious.
Stuff like this always makes me laugh at how concerned people are over continuity. It's like... c'mon. These are fictional characters here. They're not real people. Just let writers tell whatever stories they want and let good stories be good and bad stories be bad. Forget about continuity. So one writer implied that Hercules was bi once. Okay cool. So the next writer decides to shrug off that implication. This isn't the end of the world, folks.
I'm not bi but I think it was more to do with inclusion than giving a shit about continuity on the whole. That's kinda a big deal to people. We saw a similar reaction to the whole full gay escapade.
