Well, Sam's still not really thinking straight (though I expect Snow will take care of that soon), but even if he were 100%, I'm not sure he'd have a good idea on how to get home. He can't fix cars, and he wouldn't be much help tracking down our attackers. And it already bothers his professional pride that they've had to call for one ride; he's not going to be happy if they have to get another.
As a player--Sam doesn't know enough to suggest this--I'd want Sammy to try to track down the mage who made that barrier, while the rest of us try to locate the sniper or rigger who were after us. We don't have any good leads, other than the fact that someone wants us dead & knew where we'd be--and the only ones who knew that are the A-Kidz.
