"What an amazing life changing journey of magic and hope!" Morrison wrote on Instagram. "Thank you to Adam Horowitz and Eddy Kitsis for trusting me with Emma Swan. Thank you to the incredible cast and mostly, thank you to the creative team and crew of ONCE UPON A TIME. The endless hours of hard work and devotion that every crew member contributed to the show is what made magic possible every week for 7 years. I am eternally grateful to everyone. And a massive shout out, big hug, and giant thank you to all of the fans. You made ONCE what it is. You all inspired us every day. Thank you for all of the love and support for the show over the years. The #oncers made dreams come true. You are all heroes in my book!"
