Question is how many people actually should go. They don't expect to run into Sentinels, so a really large group strikes me as unrealistic, just to make contact with a newly found mutant. And if there are too many heroes around they might actually manage to prevent the Sentinels from capturing anyone (or at least as many as they are supposed to).<br/><br/>Maybe just whoever is supposed to be captured (not sure who that might be from the X-Men, if any?) plus two more, maybe three more, tops, would be best? This is just the opening of the story so it should not descend into a massive battle with a small army of mutants, I would suggest.
