Re: Rey & Anakin
People could watch, it didn't bother Anakin at all. In fact, it was part of the exercise itself, not to get distracted. The battlefield was full of distractions and interruptions, knowing when to ignore a commotion or to halt and investigate was a valuable skill.
Here, someone wanting to talk to him was hardly an imposition. He just waited for Rey to make the first move.
When she said hello, he finished the form he was in, then gracefully halted, retracting his blade.
