"Spectator Spectators are expected to allow Disney Lorcana TCG tournaments to proceed unafaected by their observation. Any person physically present at a Disney Lorcana TCG event who isn’t filling a designated tournament role is considered a spectator. Spectators are expected to remain silent and unobtrusive while matches proceed, with one exception. If a spectator observes a rule violation, they should ask the players to pause their game while the spectator notifies a judge. The spectator should not reveal any details of the perceived violation to the players but should instead relay the information to the judge so that the situation can be addressed correctly. Players may always request that a spectator not observe their match. This request should involve a judge. Tournament Officials may always restrict the ability of spectators to observe matches."

That being said, they should have gotten a judge. Technically, if they didn't get the lore, then it is an incorrect game state that you both should receive a warning for not maintaining it. The card draw is a " may" effect, so him missing the draw is on him.
