The pillow became a sofa (≧∀≦)..can someone tell me why its getting bigger?

Maybeeeee his feelings for Tiel???(づ￣ ³￣)づ

I’m thinking it grows as his bond with Tial grows. Her power is influencing his power. Making it easier to control and making him feel safer. Even if he hasn’t quite figured it out yet.

I like this theory..I hope it’s explained in the fiture chaps (≧∀≦)

As it should hahahah (≧∀≦)
