This Is Us [1] fans, now might be the time to panic. After a series of ups and downs for Randall and Beth Pearson in season three, dedicated viewers have been left questioning the fate of this beloved onscreen couple [2]. Now things are about to get even more interesting with the introduction of a new character: Beth's teacher, played by Goran Visnjić.

Visnjić is best known for his roles on ER and Timeless [3]. While the details of his new character, Vincent, are a little fuzzy, we know he'll appear in a later episode that explores Beth's backstory. Could he be her dance teacher from the ominous flash-forward? Or maybe an instructor from her past? Whenever he does make an appearance, let's hope he doesn't spell trouble for Beth and Randall.
