I feel like they could've dragged it out a bit. It's an interesting concept (not new or anything, just interesting), and it could've played well with an inner dilemma of whether he's playing with an unfair advantage.
@Saiangeli That's kind of relative. A parent could be listening in on their child's private conversations if they think it's beneficial. And it'd probably is: they might avoid the kid getting with the wrong people, or learn if they're doing drugs, or...whatever.
But you're STILL intruding into a person's private conversation. This is even worse, he's intruding in her very thoughts. That's VERY private.
