Dash and Soarin had been having a wedgie war where they kept trying to wedgie each other any chance they got. This had begun to interfere with Wonderbolts activities such as training or inspection.  
Spitfire was fed up with this and enlisted the help of several recruits to put an end to it. They found Dash and Soarin wedgying each other in the locker room and pounced on them before they could realize what was going on. They managed to tie the pair up with some rope and went to throw them into an empty locker but not before Spitfire provided the pair with a shoulder wedgie each. As the door of the locker slammed shut, Dash’s anger at Soarin overshadowed the pain of the wedgie as she began to fume at Soarin, blaming him for the pair’s predicament. Soarin couldn’t help but feel his underwear wedge up his butt and press against his nether regions while the angry mare stared him down.
 
As time passed, Dash realized that she shouldn’t be angry at Soarin but instead should be scheming with him to get back at Spitfire for sticking them in the locker like that.
