David Strauss is Henry’s older brother. He’s a highly successful surgeon at the top of his field. Before Henry’s deal with Luc, David was judgmental of Henry for being so forlorn, unambitious (he doesn’t consider Henry’s job at The Last Word legitimate work) and aimless. After Henry’s deal with Luc enchants people to see Henry as “enough” just the way he is, David is suddenly loving and attentive toward Henry. Henry is initially happy that his family appreciates him as they never have before, but in time, he realizes that their feelings aren’t voluntary or real—they’re just the curse blinding them to reality.
