In the second episode "Toil and Till" at the 1:07 mark just after the commercial, Jax, Bobby and Chibs go to Renny and Gib's house to (ostensibly) pay them for their truck ruined at the hijack of Lyn's drug shipment. After a few words, Bobby shoots Gib in the head and Chibs shoots Renny in the chest with the taped up sawed off (also used at the heist) they then plant the guns and one brick in the room and on leaving, inform Lyn they found the guys who hijacked him and give him the address. Later, Jury goes to the house and sobs "Gibby,Gibby,Gibby" while holding his body, he then recognizes the sawed off. There is a close up of Gib's dog tag, I have tried to read it, but can't make out much.
We know that Jury has put together two and two, and realizes SAMCRO was involved, but we don't know how Jury and Gib are related. Overall it is no big deal, yet it is another score to be settled with SAMCRO and as we know "paybacks are a............."
