Here’s an idea that I’ve been thinking about after seeing Rogues reaction to Natsus final comment and thinking about his future at Sabertooth and it seemed like a few people except him to leave Sabertooth. This is just an idea of how I think it may go down if he were to leave.

Sting will fight Natsu during the GMG and hopefully it would result in epic clash between the two dragon slayers, but then Natsu comes out on top in the end. So after the GMG having both competitors injured after the battle, Sting is with Rogue in the hospital or sick room resting talking about the GMG with their exceed patterns, but then Jiemma burst in enraged because of Stings defeat causing them come second or third. So with Stings second chance over Jiemma banishes him from Sabertooth, but then Rogue stands up for his friend finally speaking out against the ways of Sabertooth, telling his guild master that their guild is disgusting as they should be having fun with their comrades and not just focus on their strength as a guild and leading them into dismay over a few mistakes. He then stands between Jiemma and Sting telling them if anyone were to even try and hurt his friend in his current state, he would rip them to pieces, therefore protecting him from Jiemma's wrath. Then he claims that he wants to leave Sabertooth and find a better guild where they treat each other with respect and care for their comrades.

But this is just an idea so who knows what will happen in the later chapters.
