Oh, there's definitely a slight age difference - Jackie is fourteen and in high school and Lor & Co are in middle school. This was more of a fun little nod to them being so similar in personality and voice. Haha.And I don't think it's that the voice pool is small, I think they just have a few versatile VAs that can do multiple voices, so they know what they're getting rather than having to seek out individual VAs for each character.
