That's interesting about your younger sister. I'm an only child unfortunately. It's extremely lonely. That's why it always upsets me when I hear people complain about how annoying their siblings are. At least they have siblings...Tell me what is it about your sister that makes her seem older? Is she really smart or something?As for Zephyr Breeze I just go by what the Pony wikia tells me. In it, it says that Zephyr Breeze is Fluttershy's younger brother. Also in the episode Zephyr refers to himself as Fluttershy's "favorite little brother" as well as asks her where the love is for her "baby bro". I interpret Fluttershy to be at least two years older than Zephyr because of this. Fillyshy could be approximately 8 years old in this picture and that would mean Zephyr would fall somewhere between 5-6 years old. I also imagine ponies grow a lot like we do in that girl ponies grow taller than boys more quickly. This would explain the size differential. Though it is true we don't know how much older Fluttershy is than Zephyr. She could be 2 years. Could be 10 years. Could be 10 minutes. All we know is she's older. And since I've always wanted an older sister to cuddle with I envisioned Zephyr clinging onto his with all of his love just like I would do if I had an older sister like Fluttershy.When Zephyr was a colt (like the one pictured above) he was most likely not at all like the pony you saw in the episode. He comes from shy, sensitive, and kind kin. Needless to say Fluttershy and he probably bonded unbreakably during their childhood. I like to imagine that on especially stormy nights in the clouds growing up Zephyr would sneak into Fluttershy's room in the middle of the night and ask to sleep with her. Fluttershy, being the kind, caring, compassionate soul she is would feel more than obligated to cuddle her baby brother to sleep. (Also well Fluttershy wasn't exactly very fond of storms either. She most likely welcomed a sleeping companion during such times.) And to this day Zephyr makes Fluttershy swear never to tell anypony else about their cuddle sessions in the thunder storms. ^^I think the most confusing thing for some people about this piece is that they expect because Zephyr was "annoying" in the actual episode that that means he was always annoying. Therefore they see scenes like this with Fluttershy and Zephyr bonding and think that it can't be so. Remember however in the episode that Zephyr was simply seeking approval from his family, friends, and peers. His cry for help disguised itself as over confidence and arrogance. He's always been a genuine guy with a good heart, soft spoken, full of ambition and good intentions. It's his fear of failure that made him this way and ultimately Fluttershy became disappointed with him because of that. But no worries! It all worked itself out in the end. Now Zephyr is one of my favorite characters and "Flutter Brutter" became one of my all time favorite episodes. It's right up there with "Owl's Well That Ends Well" "Amending Fences" "Hurricane Fluttershy" "Dragon's Quest" and "Winter Wrap Up". The song "I Can Do It On My Own" was really good too. It had a great melody and was a big reason for why I really liked the episode as much as I did. I sincerely hope Zephyr returns completely redeemed in a later episode. Although something tells me Zephyr will be a one episode kind of pony unfortunately.I just found his character to be so endearing and relatable. It'd be a shame not to use him anymore. The show definitely needs more committed male characters with interesting characterization.Zephyr's hard to love, sure. But it's in my humble opinion that he's waaaaaaaaaaaay harder to hate. I think the scene above shows why.
