Crowley and Gideon
Gideon's own limited experiences with demon was far different from this - mainly just watching helplessly as a disembodied voice when they attempted to - or actually did - possess a member of the Waverider's crew and forced them to hurt others. This meant that she had no idea Crowley was anything other than human at the moment.
She tilted her head as she studied his plate and compared it to her own, and since he offered she reached out to pick up something that she had missed, and slipped it into her mouth. After swallowing, she gave him a smile. "Thank you, Crowley. It's very good."
