Trivia: Luke Goss plays the villain Nomak. Six year later, he would play the villain Prince Nuada in "Blade II" director Guillermo del Toro's "Hellboy II: The Golden Army." Both characters have some notable similarities, including pale skin, the fact they both kill their fathers, and the fact that their sisters team up with the heroes.
Trivia: In the original script by David S. Goyer, the Reapers were much larger, more intricate in design and had many more monstrous features. Director Guillermo del Toro eventually reworked them into being much simpler creatures that were similar to regular vampires save for their pale skin and split jaws. He felt this made them scarier since they could blend in better.
Chosen answer: Killing Scud with it probably was more satisfying for Blade than Reinhardt, who he easily beat as well. He hates familiars and that moment he used the bomb to have Scud reveal his betrayal, and then kill him, so he won't get away. Reinhardt he knew would not try to run, he was killing him anyway.

Agreed. I saw it as he was waiting for Scud to show his hand. Like Blade said, he knew Scud was a traitor/a familiar the moment they turned him. He was waiting for the perfect time to let Scud know that he was already well informed on his betrayal, and that his azz was now cooked. Doing it that way was way more satisfying for Blade.
