I don't even remember what you're referring to, but thanks! I recall drawing Lava and Glaucus with aids once... I only drew Liz with an implied wheelchair in a doodle, so I'd like to put her in a proper one someday.
On a lesser note, I've come to headcanoning Talulah wearing some sort of knee brace, based on her original Ursus military outfit. Quartz is actually missing an eye to warrant wearing an eyepatch, not just hiding her scarred one. So on and so forth; it's nice to think about debilitating conditions if canon is too scared to.
