“Moooooom! PLEASE!” Perseus piteously looked at the mother asks for her permission. “Let me use just a little bit of chaos, here, in Ponyville, i just wanna to show one new trick to my friends!”
 
“Really?” Fluttershy looked at her son with some disbelief and a slight smile. “Yes, I remember when the last time you asked me about the same thing, but instead of showing “harmless”, as you said, teleportation, you created a huge dino-piranha monster that nearly destroyed the whole city. So my answear is NO.”
 
“It was an accident, I didn’t want to, by the way, I was small then and not very much controled my power…”
 
‘Um, Perseus… It was two weeks ago…”
 
“Weeeeell, you see, now i’m older by TWO weeks!”
 
“I’m sorry dear, but no.”
 
“Please…” He looked at his mother with the eyes of a sad puppy, imploring her to change the decision.
 
“Oh sweetie, don’t make this eyes again, that won’t help…you…”
 
Looking at her with the same gaze
 
“Ok… you can do that…”
 
‘Yeees!” Joyfully jumping, he exclaimed. “You’re the best mom in a whole Equestria and other five trillion dimensions! Love ya, bye!” He snapped his fingers and disappeared.
 
“Ahh… teens…”
 

 
Well, some interact situation of Fluttershy and teen Perseus.
 
Perseus can use his chaos magic, but only in the Discord’s dimension. He respects and even afraid of his mother, and usually asks her opinion first, but in the last time he argued with the Thunder Fether that he could make a huge monster, but everything got out of his control, but thanks to his father everything ended favorably. And from that moment Fluttershy began to trust him less, but she can not resist his puppy eyes…XD
 
Year, Perseus can use his cunning and poor eyes when he need that.
