Help? Klein repeated the word silently and was momentarily a little stumped.
Back when Sharron had taken on the mission of protecting him for three days, it was mostly because of the money. For a Sequence 5 expert to be willing to take on such a mission was, in itself, a low probability. It could be chanced upon, but it wasn't something that could be forced. Furthermore, back then, Klein was desperately trying to save himself and was so frantic that he wasn't willing to give up any sliver of hope. As such, he still felt very grateful for being able to receive the help of such a powerful Beyonder, even if it was because of the money.
However, that was all. He wouldn't recklessly interfere in an unknown, dangerous situation in complete disregard of his own strength and circumstances for the sake of the other party.
