team member(s) faking or presumed dead

[ladyhatshepsut]

 I'd like to see any stories where one or more of the Seven if either presumed dead by the others or is faking his death for some reason.  One of those I've read in the past, and am looking for again, is where a body is found at the CDC; since the shotgun blast destroyed the features, they think it's Buck, who's actually out picking up someone's birthday present and doesn't know what's going on.

Another one has ATF Agent Tanner calling his old army captain Jim Ellison when he thinks his team is all dead and he's being stalked by an old enemy.

Any others would be greatly appreciated.
