When Ilari Filppula moved to the KHL, Teräväinen was put in as the first line centerman for Jokerit. He, however, started the season pretty slowly, and only scored two points in the first nine games. He was able to eventually pick up his game, and after a successful tournament at the World Junior Championships, he went on to a 13 game point streak, where he scored five goals and 18 assists. He ended the season with 44 points in 49 games.
