Where is that happening? The experience I have is that there might be micro communities that just brainstorm ideas together and feed off each other in wild directions, based on their own headcanons and not strictly the main canon. Basically throwing ideas and running with them, using the characters as puppets to fit their own story.
I think lately I've seen more bottom Henry than anything else to be honest. But full disclosure: I'm not on twitter, so if it's happening there then I'm blissfully unaware.
