It's time to read the "Writing on the Wall". Well, try to read the writing/carving on the wall. Coulson can't stop his carving compulsion now. And when a former SHIELD agent turns up dead, with the alien symbols carved into her, our heroes have to track the madman behind it. The only way they can do that, though, is by making Coulson dangerously recall his magical place memories. But in triggering his memories, they may have turned him into the same kind of obsessed madman they were chasing. And the other half of the team is trying to track down the ever vigilant Grant Ward, who turns out to be much more clever than they can handle. Jay and Josh relive their memories on this week's Agents of S.H.I.E.L.D. Case Files. Download now, to decrypt the data-stream directly to your MP3 player!
