Sorin's intervention was far from necessary--and, in fact, all it did was paint a target on his back. At least he wouldn't be entirely unaware: the look of hatred in the vampire's direction made Archer's disagreement with Vash look like sunshine and roses. Whilst Vash's philosophy was the most painfully naive that the Heroic Spirit had ever been exposed to, it was simply that--naive. He might think the blonde man an idiot and his views a painful reminder of the attitude that lead to his current existence... but it wasn't something that went [i]against[/i] the tanned man's principles to such an extent. The look lasted only an instant, then Archer was headed up the hill once again, now planning to keep an eye on Sorin and learn his abilities and weaknesses, as well as how to deal with him either when this was over or if he turned on the rest in his own interests. Saber, at least, could be relied upon to side against him if his views became common knowledge.
