In the episode, Kate (Dakota Johnson) decides to go back to college and is determined to focus on her studies, despite encouragement from BJ (Lucy Punch) to cut loose and have fun. Kate and BJ take an ethics class together that's taught by Annable's character, Greg — who "doesn't always practice what he teaches."
Annable most recently starred on the canceled ABC show 666 Park Avenue. His Ben and Kate episode is scheduled to air on Tuesday, Feb. 26."
