I'm sorry I don't know it exactly. But I am almost positive that it is either ';Saviors'; or ';House Divided';. Those are episodes 21 and 22, respectively, in season 5. I remember because it was one of the ones when he was hallucinating Amber and she helps him solve a case, and those are the episodes where she does that.





Now that I think about it, I'm pretty sure it's ';Saviors';. But not positive.
';House Divided'; good ep!
