Someone's clearly playing a Zelda game off-panel in panel 2. It's the only explanation.
Panel three is bound to confuse many, and it's easy to understand why if one considers their own feelings fairly rational, and is in agreement with them.
I, however, share many of Susan's phobias and anxieties, and I know that feel.
Relevant pony form is relevant, though Susan's REALLY unlikely to choose that one in spite of how she felt while in it.
