Asgore, I think just does not know anything about Ralsei (even using ‘it’ as in; “it is a person”)?

Character screen having that is definitely an indicator of Ralsei being trans though. (and the other previous hints too obviously, for me as back as ch3)

Also I love this part of your post, forgot to say, can’t agree more.

I think that’s most of the main stuff, this gay little goat is seriously the eggiest character i have ever seen in any piece of media
