Comments of chapter undefined of The Greatest Sinner

Like I reieterated in a previous chapter. I enjoy Evan the character solo no attachments to anything except his goals. This girl is becoming incredibly annoying as a character, if she just tags along throughout the story, taking more time from the main MC. Why would Evan teach her a spell from the Lion Sigil one of his greatest secrets should be kept for himself. I sincerely hope Evan gets rid of her soon when her usefulness is over for his experiments.
