Charles being a girl?!

Hey guys, so I have a new theory for you guys. Ok so remember back to 5B finale, the girls got locked in house or ''Doll house'' and in the doll house, the was a path, and there was a women's voice saying ''Follow the lighted pathway'' And as you know, we thought Charles was a mans/boys name. There could be a chance Charles is a girl as Charles is sort for Charlotte, which we all know is a girls name. I might just be over thinking this, but there is a change that Charles is a girl. Or maybe the voice we heard might be apart of the -A Team :) Ok, so leave your theories in the comments below.....Bye!
