Are there any other queer identities they have/you're headcanoning them with, apart from being aspec? If not, just say no. (For example, someone is an aromantic (headcanon) lesbian (canon).) Also ensure that any queer identity you're headcanoning them as does not cancel out any canonical queer identity they already have! And please make sure an identity is canon before saying it is, because I don't want to spread false information.
Ensure that there is a maximum of 3 LGBTQIA+ identities mentioned in this form, due to the Twitter image limit being 4 (excluding an image of the character).
