Smeags why are you so complicit with the way this information was handled?
You completely and utterly trusted sparks, and have gone along with this info without the single thought that he might be scum.
You have no beaststone. Your only conclusion should have been that you were stolen from, not swapped. You have no proof of sparks truthfulness. For all you know, sparks should be a liar, or you should at least be having some questions.
