Of course they know.
People really need to read the article because Mark Ruffalo’s response was amazing.
He did not ridicule the fans for their slash art. He didn’t say they were gross. He instead GOT EXCITED and praised them for being so creative and taking the characters to heart and running with them.
Also, ugh those fucking two they are so cute
*DIES AND FALLS IN GRAVE AND SOUL GOES INTO SPACE* my god that was cute
everybody stop what you’re doing, its a cat cleaning a baby
"Stupid furless humans can’t take care of their kitten, I have to do everything myself."
My favourite thing is baby sitting up thinking “What the fuck is that?” Then seeing the cat, thinks “Very well, continue.”
