I don't know how you trigger it but there is one scene where Jamie gains a little bit of weight, but i loaded before going further as I didn't know if it prevented Jamie from meeting the fairy or not and I don't know how to trigger Jamie meeting the fairy
Its honestly stuff like this that maes me think there should be a wiki or an in game guide of some kind for these obscure things, maybe not like a direct this is how to get this to happen, but like a vauge "a certain type of object can cause (insert event here) to happen"
