yes
The informant is talking about mercy killing AJ and Sharpe says "I see". Aj does not really know the context of this conversation other than he knows he's supposed to die, so he's understandably shaken and scared. He runs to put his shoes and jacket on to run away, saying he's such an idiot for trusting Sharpe. Sharpe and the informant hear AJ run away in the car and the informant books it to chase after him. Sharpe is having none of this and he grabs the informants head, leading to a brawl. Eventually Sharpe subdues the informant by kicking his spine, which I assume he did some major damage seeing as the SFX was "crunch," and the dude couldn't move anymore. Then what it looks like Sharpe did after: TWIST THE INFORMANTS NECK TO KILL HIM. This had me shocked ngl, it's the first time we've seen Sharpe be willingly violent. You can tell that this whole situation has Sharpe pissed. It took so long for him and Aj to trust one another just for it to all be shattered by this informant. It's very clear now that Sharpe values AJ more than his job. How far he'll go for AJ? More to see in the future.
OMG Ty queen! Also, I wish the uploader could just pass the mantle to someone else if they've dropped this manhwa :(
