Situation with Tara is interesting. But why we all thinking that Ryan with Stetler confront to Tara. I know, i read spoiler, but maybe they do this not together? Ryan finding drugs, talks with Tara, she have some excuse for this (i hope so), but Ryan is angry at her, cuz it means trouble for lab (maybe IAB start checking everyone on stealing). Then somehow Stetler finds out that drugs was missing (some of vics siblings says that pills is missing) and come in morgue, and suspect Tara. Its can be possible About 7x20. This heck around his neck is connecting with feet, if he moving too much this thing strangle him, so he should be in one position, that means that he wouldn't resistance that much. I saw something like that in Law and Order (i guess), the cord was between vics neck and feet, if she tired and make her leg straight, she will strangle herself.
