the way that radiant healing and the surge of progression (regrowth) works, is by making someones body the way they see themselves. even old wounds can be healed this way, as long as the person doesnt yet accept their current body. this is demonstraded by lopen healing their arm.
so what would happen if a trans person (or generally any person with body dysmorthia) who doesnt accept their current body were healed this way? in my unchangable opionion, their body should transform to how they see themselves, physically transitioning them! i imagine a closeted, radiant trans person sucking in storm light for the first time and suddenly changing their appearance, to the surprise of everyone
