About Jirachi's whishes, can he give 3 in total or 3 every time he wakes up from hibernation when the comet comes, or is it unlimited? I think I read that in the manga Jirachi can only grant 3 wishes because they are written on the tags and once a tag is used it's used, but I don't know if the same limitations were used in the anime.
You know how in anime sometimes a stoic character does a thumbs up and stars appear around him because they feel they did a good job. That is how I imagine Nethan is doing the thumbs up to Gavin. He thinks he nailed it.
