Was easy to miss. Sean tells Christian while still in jail that the bottle of tranquilizer was found by the police in his nightstand. Sean has that look like 'they got ya dead to rights, buddy'.....

But remember in a not too previous episode about the girl that was under anesthesia and could remember what was being said about her while in surgery? And was threatening to sue? Christian and the anesthesiologist did the experiment on Christian to see if it was possible? That bottle of tranquilizer.

Christian didn't say anything about it to Sean to see what Sean really thought about his guilt. Assuming here that Christian knowing he was innocent, that is.

Also, I think Christian did not want to involve Sean in a potential f-up in the office just yet. Yes, the newbie partner was in on that one too.
