Roswell, New Mexico showrunner Carina MacKenzie shared the news on Twitter, confessing that the idea came to her in a “sleeping-pill-induced” stroke of genius. The sleepy scheme caused MacKenzie to text the actress, whom she had “never met,” in the middle of the night to beg her to join the show.

MacKenzie also shared a few more interesting tidbits and “very mild spoilers” for Roswell, New Mexico season 2. Check out all of her tweets here!

We can’t wait to meet Liz’s mom, to see another flashback and to find out whose sexuality shifts in season 2! As someone who’s always been terrified of the spooky Dawson’s Creek Halloween episodes, we’ll start preparing for that one now.
