[Of course Jack remembers dying; he'd been there when it had happened, after all. But that's not what's important currently. Currently, the upset little man still half-wrapped in his body bag believes he's Handsome Jack. Handsome Jack's death is something that Jack doesn't remember, probably by virtue of that death taking place after his own. So. Naturally he's very curious to find out how his boss died.]

Uh. Hey? Guy. [He squints at the helpful nametag still peeking out from the end of the body bag.] Uh. Vaughn? Pull yourself together there, buddy. This reeeeeally isn't the time or place for a full-on emotional and/or mental breakdown.

[Sorry, friend, can't hold; please engage.]
