okay i will bite....
they are the bestest of best friends
he was grateful that she saved his life
she flew off with him at end of sonic rainboom
he was grateful that she saved his pie and tried talking to her at the gala
liked Dash so much he danced with Dash at the royal wedding and the same for Dash
he was happy to see Dash in rainbow falls
he was very grateful she saved his hide again
she was happy he said that
he was happy knowing Dash had great friends
she helped him out when she finally figured out what Spitfire and Fleetfoot were up to
he cheered her on when Dash was qualifying
he was very happy to see her in Rarity Investigates, even told her that if it wern't for Rarity she be talking and hanging out with him.
he as the then leader of the Wonderbolts in Spitfires absence gave Dash the chance to fly with them in the show
she was so elated that Soarin gave her the opportunity
he as the then leader of the Wonderbolts in Spitfires absence gave Dash the chance to clear her name.
he tore Windrider a new one once he found out he set Dash up
he was the only one to ask if Dash was alright when she landed in the trash can in Newbie Dash
he was the only one that did not go out of his way to make fun of Dash
she choose Soarin to flirt with when doing her Rarity impersonation
she choose to stand on Soarins bed and watch him sleep until he woke up to do her Pinkie Pie impersonation.
he was the first one to tell Dash that she is meant to be Wonderbolt and that she is an awesome flyer
when telling Dash about the awesome roller coaster he didn't just simply stand there and tell her about it, but rather was totally hanging on her and embracing her while telling Dash about it.
when Soarin ran away in self shame from the Wonderbolts it was Dash Spitfire tasked with in bringing him back.
She was more than happy to tell him that he was not a screw up and told him to remember all the all the times she screwed up even told him he's the glue that holds the team together!
so yeah what you said is absolutely FALSE 100%
They are very great life long friends. and thats something that you and any other troll can't ever take away.
