Okay, Andrew had known for a long time that he felt a different love for Jack than Jack professed to feel for him at times, but he hadn't known it would drive him to these lengths; he was about to try and face one of his phobias and it was all because he had trouble saying no to Jack.
His hand in Jack's was cold, the fear he was already feeling just from the anticipation of flying turning his blood cold, making him shiver and he wasn't even on the broom yet.
He tried giving Jack a smile back for his troubles but it was weak and disappeared almost as soon as it had appeared. "Sure, yeah, okay." he agreed, nodding his head while his grip on Jack's hand just got tighter and tighter.
