You can. If I were you, I would try to use your character inner thoughts to try and start it off. You can do that by using italics. Here's an example:
(Based on a different show, Riverdale. I'm using the last sentence from your story to show you how it would work)

How did that happen? Betty thought to herself as she shook her head.
I hope you undertood that and that it helps.
