... I finish the last of my tea. The others are lingering over theirs, shooting furtive glances between them as they silently debate the best way to talk me out of my decision, but my mind is made up. "I'll be fine, girls. Really." I rise from my seat and circle the table giving each one of them the most comforting hug I can manage. Lifting my bags up onto my back, I pay for the tea and then head for an empty field behind the restaurant followed by the others. I’ve already prepped the spell that I read out of Star Swirl’s notes, the one-way ticket to wherever and whenever he ended up. Getting back will be up to me, but I have a few options that should work.
