Red text isn't an entity. It originated when whoever uses it saw me using blue for Ninjakitty, and you using Italics for Alice. They were confused and asked "what's with the blue text" and after a short explanation they used red to have conversations with themselves. Like the idea of a self insert character that the author talks to in a story, a very common and stupid cliche.
"What a strange thing to do. What kind of lunatic has conversations with themselves?" I know, right? It's weird.
Don't you just love the fourth wall? "It is very nicely decorated. Really Alice, I'm surprised you put so much effort into that one wall."
"Pirate Dog chose the decor. He has a good eye for color." Which is odd, because I'm pretty sure he's colorblind.
"Dogs cannot see color, unless Pirate Dog is also an alien, in which case I highly doubt canines would evolve on more than one planet simultaneously." Anything can happen in an ever-expanding universe. "Ever slammed a revolving door, sir?" Except that.
"Pirate Dog was my high school science fair project. I was trying to genetically engineer the perfect companion, and I read an article about how loyal Terran dogs were. I went to Earth, took some samples, did some science, and nineteen lunar cycles later I had a genetically perfect puppy. I still can't believe I came in second to Mar'ci Wunup." Pirate Dog is an extraterrestrial created from terrestrial DNA. Does that clear things up?
Hate to break it to you, but you CAN slam a revolving door. All you have to do is change the circumstances of the door. Just extend the wall next to the door slightly, and you will be able to slam the revolving door against it all you want.
"Hey guys, what's up?" Oh, hello Sunset. Glad to see that you've made it to the club of members and their companions.
"Hey, guys! Did I miss anything?" Oh, not much, Rainbow Dash. Not much at all. "Glad you could make it." "Well, Crimson's waifu showed up, so two can play at THAT game!"
"Well, this place is becoming crowded now! Are you sure that we should be in here, you know what Dash is like around you "I'm fine, Sunset." "Let's hope that Dash doesn't try to flirt with you again. Remember last time?" "Oh yeah...."
