It was the usual long-winded speech about love and commitment. He may have even quoted a few bible verses. They pretended to listen to him until he got to the important parts.
The priest asked Angel if he would take Buffy as his wife.
"I will," Angel said.
When asked about Angel, Buffy replied likewise.
"Do you have the rings?" asked the priest.
Angel and Buffy pulled out the wedding rings. One after the other, they put the rings on each other's hands.
"I now pronounce you man and wife. You may now kiss the bride."
With that, Angel removed the veil from Buffy's face, and they shared a passionate kiss. Noticing the priest taking his leave, the newlyweds figured they should be on their way too. Buffy seemed to have no trouble making her way back trough the aisle, as though she was used to dresses with big skirts. He had no doubt, though, that she was planning to change out of it the first chance she got.
They were soon out on the front steps, ready to take on the world as husband and wife. Just then, he noticed a cigarette a passer-by had carelessly left burning by the entrance.
"Buffy look out!" he said.
It was too late; her dress brushed against the cigarette and caught fire. "Angel?" she said.
Angel rushed over to her and tried putting out the fire; he was unsuccessful. "Wait here, Buffy, I'm going to get help."
"But, Angel -!"
"I want you to stay put," he said, a bit more firmly this time.
She nodded, and watched as he ran down a road into the nearby town. Reluctantly, she had to admit he was right; her large skirt would slow them down too much.
She could only stand there as the flames worked their way up her dress. There was no one around to witness her distress, the priest having left by this point. She couldn't recall ever feeling this helpless in her life, or being so scared.
Still, she took comfort in her belief that Angel would return in time to save her. In fact, she couldn't help finding this whole situation oddly romantic.
