I changed the post to something more fitting to the narrative.
Took me a visit to Wikipedia to understand the meaning of "mirroring each other" (English is not my native language) and I've took extra care in re-reading and proofreading the previous posts in order to make more sense. 

The most difficult part was to take the mirroring one another part to an extent that it not only refers to the studying part, but also Zaph's dust cloud spell. I really wanted to make something interesting like this.
