I'm one of the people who really loves making this show's universe come to life and wanting everything shown in the show to make sense, but because a wide shot of a room like this needs to look "full" in animation due to the pan from left to right, the storyboarders filled it in with a lot of extra characters. I also doubt the captain would sleep in the same room as the rest of the members.
From AKR's "The Elements of Harmony Guidebook,"
THE WONDERBOLTS are an elite squad of Pegasus ponies who perform amazing aerial feats of derring-do at competitions across the lands of Equestria. SPITFIRE is team captain and a spirited competitor. SOARIN loves blazing a trail through the clouds—but only when he's not chowing down on one of Applejack's pies. Other team members include Blaze, Fire Streak, Fleetfoot, High Winds, Lightning Streak, Misty Fly, Rapidfire, Silver Lining, Surprise, and Wave Chill.
I suppose if we really wanted to stretch our imaginations, we could say there are "show" Wonderbolts (the six or seven or whatever random number fits the current animation scene) who do all the acrobatics, and all of the Wonderbolts do things like fight dragons, evil queens, and other villains. Or they trade off depending on their speciality. I'm not sure the show-runners really have a firm grasp on what exactly the Wonderbolts are from episode to episode, I'm not sure they care, and as much as I want it to, I don't know if it really makes a difference. It wasn't until season 4 or so that
Spitfire and
Soarin' got their own cutie marks: The photo of Dash with Soarin' in Canterlot Wedding showed Soarin's cutie mark as the generic Wonderbolts logo, but later in Rainbow Falls he had his own unique 'mark.
Over time, the show's grown up and taken itself more seriously, but it's not lost what made it fun and special to begin with. What was once a placeholder (like a temporary cutie mark) can be developed over time, and while you can't erase the past animation, that doesn't need to invalidate what the producers, animators, and actors want to do with the Property in the future. The show is rich as well as constantly developing, and that's one of the things that makes it so special to me.
On a lighter topic, Soarin' always looks "old" and "tired," but I think the line under his eye makes him look distinct. Besides, Matt Hill's plays Soarin' with such a cool voice (mature and raspy but enthusiastic) I can't help but love him.
