Welcome the Whirlwind, well minus Angelus but he is mentioned a lot in the first chapter of Peter David's tale. In the first episode of season 5 of Buffy we meet Dracula for the first time. Yes in this verse he is real. And he can do all the amazing things that he can do in the books. Normal vampires can't but he is different, he is better he is after all Xander's master.
In the episode Spike tells the Scooby gang that Dracula owes him 11 pounds. He didn't go into detail about the why or how they know each other, so welcome to these five chapters that give us all the information that we need.
In this first chapter we learn that Dracula was in love with the Gypsies who cursed Angel and wanted revenge on Darla and Drusilla because he wasn't sure which one killed her. He knew that the three of them killed the rest of the clan and for that they all had to pay.
Dracula hypnotized Dru and Darla to come with him and love him. They wanted to be his brides, he asked them to kill each other and they wanted to but Spike got the villagers to attack him and got the girls out just in time.
Now how does this explain the money? Well Spike bought Dru a signed copy of Dracula as a gift and Dracula threw it into a fire pit. Spike wanted to be repaid for it. After all back then it was a lot of money. He even tells him in a note as he saves the girls that he will be back for his money.
This is a great addition to the Buffyverse, it's fun and catches the voices of the different whirlwind members well. The only thing that bothers me about this issue is when Spike talks about Angelus being cursed. No one knows about that except for Darla. She wouldn't tell Spike or Dru, they kept asking but she wouldn't tell them. That's why Angel came and hung out with them for a while. Because they didn't know and Darla wanted to believe that he could still behave like Angelus. Spoiler, he couldn't. Spike still didn't know that Angel had a soul in season 2 episode 3 School Hard, when Spike first showed up in Sunnydale. That is a mistake that bothers the hell out of me. Other than that this is a great first issue to a great series.
