I see now that those spoilers were bullshyt (said Walt would kill Declan, Marie would not find out, ect) so I now believe that Todds people re who the M60 is for. I have a different perspective about Hank though. Him and Marie are prob the least broken bad, so I do think Todds people will kill Skylar while Walt is on the run or he leaves after she is killed. Upon his return with the M60 Hank will no longer be with the DEA, Hank will find out Walt is back, Hank mad about the death of Skylar and wanting revenge also will ride with Walt to either save Jesse and avenge the death of Skylar. Wishful thinking but possible.
