Gren and friends org betrayed Merciful (Jakes org) so as a punishment as what u guys already know for sure, is they kill those who betrayed them. Jakes the one who always cleans the mess. Im not sure tho if he killed Gren. And ofc, Jake already know who Gren is and Shins got to know about it too and tried to save/talk to gren and he got to his grens house to talk to him. The guy who almost collided with him (Shin) at the road was Jakes ally, hes trying to stop Shin from going to Gren (which was Jake's instructions). at the last panel, things will get messy cos Gren was Shins important person and Jake's enemy. The latter needs to decide what to do, and he decided to lock up Shin? Hes jelly ?
This is what I understand in this chapter. Bye.

THANKYOU SM FOR THE EXPLANATION I WAS A LIL LOST 
Jake shot 3 times and there were 3 ppl so he probably did shot Gren
There were 4 people in the car but 3 shots!
for sure jake didnt kill any of them cuz they had vests, he even asked them if they had some, so gran and others are still alive for sure. im not convinced if jake is from merciful tho, whole 2nd part of this chapter tilts more to a cop side of jake
