Rebellion within Sabertooth

Rebellion within Sabertooth is an event that takes place during the Grand Magic Games arc.

Prologue
At Crocus Gardens, Jiemma asks Sting and Rogue regarding their loss against Natsu and Gajeel and the "disgrace" they brought to Sabertooth with this. Rogue admits, that Natsu was just stronger, which enrages Jiemma. The Guild Master demands that they remove their Guild Marks, however, Lector tries to defend them. Jiemma doesn't recognize Lector and gets angrier when the Exceed shows Sabertooth's Guild Mark. Then, he vaporizes Lector with a blast of Magic, really suprising the rest of the Guild. Rogue covers his own Exceed, Frosch, afraid that he comes next.

Rebellion
Sting starts crying and yelling in shock and mourning. When Jiemma is just about to scold the White Dragon Slayer further, Sting eventually unleashes a lethal blast of Magic towards Jiemma, piercing through the Guild Master's chest. This unpredicted event really shocks the Guild, however, Minerva actually seems pleased.

Aftermath
Minerva congratulates Sting, because he surpassed the current Guild Master in power, thus being the next candidate for the the title. Jiemma tries to speak, but Minerva tells him to be quiet, because (according to his own logic) he has no right to speak. She then explains to Sting that he lacks the thing called "power of feelings" and tells him, that she saved Lector. Sting begs her to give him back, but Minerva says that she only gives Lector back, if the team wins the event on Day 5, proving that Sabertooth is the strongest.
