*This is a script of a fan-imagined episode of MLP:FiM whose canon and tone is to match those of the actual show.*
Rainbow Dash nearly runs into a sea-green pegasus pony. He is introduced as Seeker, a pony who flies high above Equestria, using what he sees to make maps so no pony gets lost. Partly thanks to the enthusiasm of Pinkie Pie, Seeker is introduced to others within the show's six main characters. Rainbow Dash challenges Seeker to a race and wins, but then notices Seeker taking off to a level of the atmosphere higher than any Rainbow Dash has ever experienced. Because of Rainbow Dash's expectation of herself to be the greatest flier of anyone she knows, she finds herself unable to handle the fact that another pony is outdoing her in something related to her expertise, even if it's simply the height at which a pony is flying. This leads Rainbow Dash to perform some damaging actions, some with more destructive potential than others…
