Sorry, didn't explain myself well. I knew it was the real hammer. My point is that Thursday didn't plant the fake one, his partner did. I'm not sure Fred had actual knowledge that his partner planted it. And now that he knew that his partner "cheated" with the evidence Thursday was willing to give himself up. He would have but Morse took matters into his own hands. To me, that made Thursday a stand up guy.
Now, what's happening with Box,Thursday, and the envelope of money, well I hope it's not what it looks like. I still have hope that Thursday does the right thing. It will break my heart if he turns out to be crooked.
