What season were those episodes in when the Texas Rangers teamed up with a NYPD Cop to stop assasinations of federal agants? Its the one with Buzz, the hacker from Prison. I wanna buy the season these eps were in.

The names of the episodes are The Winds of Change, Lazarus, Turning Point and Retribution. You will find them on the Final Season Box Set. Hope this helped.

Oh the Task Force episodes really freaked me out. I missed the first one, so when I saw the second, Walker was at the "headquarters" and I had no idea how his office area changed to state-of-the-art. It was good TV though, and I was glad when they went back to normal.
