You can’t normally tell because Connie usually wears loose clothes. However, I was looking at Connie in her training outfit, and I noticed something:



Throughout Sworn to the Sword, she’s completely flat-chested.

However, in Mindful Education, she appears to have a trace of a chest.

This is pretty much consistent throughout each episode, short of the freefall in Mindful Education, which may be because she was pulling her head back, stretching her upper torso thin. The two eps both also had multiple storyboard artists, with Jeff Liu on both, so it seems unlikely to just be a difference in storyboard artists - considering that it’s consistent, he probably would have helped with putting it in there. Also, I’m pretty sure different animators work on different scenes simultaneously (gets an ep. done sooner), so I doubt it’s an art-style difference on that front, either.

Connie is around that age, so it does make sense. Heck, 12 ¾ years? She’s a fair bit older than I was. (I was kind of an early bloomer. ^_^; )
