Twilight sparkle has a lot to accomplish, but she has a schedule, so for the most part isnt' that worried. The Smooze is dangerous, but she has the solution to that problem well in hoof. Asgard isn't by any means safe, especially when she finds it has it's own resident chaos god (or maybe goddess, that part is confusing) but she's at least mostly prepared. After all Twilight brought Blossomforth and Sweetsong, two of Luna's guards just in case a fight is required. At the end of the trip Luna meeting with her long abandoned daughter and queen of the bat ponies can't be planned for well and could end very badly, but it probably won't. Yet most terrifying is meeting a seemingly normal earth pony mare who lives in Reinia, in a village outside Mooscow. Spike and her other traveling companions can't figure out why that worries Twilight the most.
