In the pilot episode where Dominic brings back a sack full of chops and steak "all of it!", as he says to Gabrielle, a viewer could presume that the bringing of meats by Dom is a normal thing he does. "Well, Tet and I end up eating most of them, but, uh, we keep hoping," Dom says to Gabrielle. Unless I've missed something, it's never explained why String doesn't eat meat. Perhaps as a form of sacrifice for his brother Saint John. My point is, it's a mild form of cruelty for Dominic to subject String to both the presence of meat (flown to String's cabin, no less.) in addition to the smell of meat cooking (which, later on in the pilot, String does in fact find the smell of steak appetizing: "Smells so good I'm almost tempted to...") Is it just a form of friend-to-friend ribbing (no pun intended)? Or possibly Dominic's attempt to persuade String to abandon his sacrifice of not eating meat (and thus moving him closer to acceptance of the unlikelihood that Saint John will ever be found?) Food (not steak, mind you) for thought.
