She had to be methodical, even under pressure. Pull the magic ... that was the first step. So she tried, but it wasn't as easy and effortless as Harry made it look. It was like trying to catch a pebble in a raging ocean swell. It skimmed and shimmied away from her grasp, and each failed attempt left her annoyed and frustrated.
