ABC announced on Thursday, January 15, that Susan Kelechi Watson joins High Potential as "a woman from Karadec's past - wry, open-hearted, and independent." According to the official character description, Watson's character is "always chasing what's next, not out of recklessness, but out of a real appetite for life. She follows her curiosity wherever it leads, whether that's a new city, a new flavor, or a new chapter.
