Raph didnt feel the need to come out properly, he just sorta ordered a flag online and when it arrived he held it up to shake out the creases and that's sorta how he came out as pan, nothing big, nothing he felt the need to be scared over, he knew at least two of his brothers were LGBT so he felt comfortable.

He ended up buying everybody their respectful flags for Christmas and splinter even bought the family a rainbow flag to put in the main room, it hangs proudly on the wall and they have a family picture of them standing in front of it, April included.
