Learning how to cloak her magic did not come as easily to Hermione as she hoped it would. For too much of her life she had taken for granted how quickly spells came to her. Even without much practice or thought, she was able to perform some of the most difficult magic there was. When she first joined the wizarding world as an obnoxious eleven year old intent on learning everything that she could, she made great strides to be successful as a way to prove to those around her that she deserved to be there. Likewise, in the years she was under Antonin's tutelage, she worked hard to prove that she was just as worthy of the Mark on her arm as anyone else. A thirst to show everyone what she was capable of had been her motivation for most of her life.
