When Rainbow Dash showed Tornadio to her house in Cloudsdale, Sprik saw her boyfriend.
"Tornadio! You're in Ponyville!" Sprik said, excitedly.
"Sprik! Inferno sent me here to find you. I've been so worried," Tornadio said, hugging his girlfriend.
"Wait. This is your boyfriend?" Rainbow inquired.
"Yes, I am her boyfriend. Got a problem with it?" Tornadio questioned.
"No, I just think that you're awesome, having the same manecut as me. What's your Cutie Mark?"
"Cutie Mark?" Tornadio asked, confused.
"Talent Tattoo," Sprik clarified.
"Oh. My Cutie Mark is a Tornado, marking me as a son of Hurricane, god of the winds."
"K. Sprik, what do you say that you introduce him to the others?" Rainbow Dash said, nudging Sprik.
"Sure."
"Just be careful at the Pink's place," Rainbow cautioned.
"We will. Geez, RD."
"Who are you?" Tornadio wanted to know.
"Rainbow Dash, the best flier in Equestria, after the Wonderbolts, of course, and the bearer of the Element of Loyalty."
How do you pronounce Sprik?
Sp-rick
I like the idea, but you need more than dialogue to pull it off. Add some descriptive text to help people visualize what is going on. Maybe let us in on what Sprik is feeling, or maybe the other ponies. What you have is good, but need more narrative.
