Frame 1: "Hello everypony, as Im sure you know I have been helping Snails lately. As such I will be answering the most frequent and sensitive question you all have sent him."
Frame 2: "There are two spells that change a ponies gender. The first being the traditional swapper". It takes what you are and makes you what you are not."
"This change naturally corrects itself between 3 to 72 hours depending on the caster. Starswirls lasted 40 hours."
Frame 3: "When cast on ponies with gender-dysphoria there are two possible outcomes. The first being the spell recognizing the pony as already not who they are meant to be. And thus fails."
"This is the most common result."
Frame 4: "The second being the spell does not recognize their discrepancy and changes them anyway. The problem being the spell does not change the dysphoria. This is almost always traumatic to already confused individuals."
"This only happens when the caster is inexperienced."
Frame 5: "The second spell is actually two separate spells. One for each transition. These spells involve a long process of rituals and hormone therapy. The process takes years, and the change is irreversible."
"Because of this the screening process is rigorous. Snails is also too young to begin hormone therapy."
Frame 6: "That is of course assuming Snails is even transgender. If I recall he has not decided what he identifies as yet. Dont be so quick to define him just yet."
"The poor darling is only fourteen after all."
"I hope this answered all of your gender-bending" questions."
