Questions about World Record and Kid's Story
World Record: when he woke up in real life, the machine just suppressed him back to sleep. This is different than what happened when Neo first woke up in Matrix 1 - the machine disconnected him and flushed him out as garbage. Why didn't the machine flush out the athlete when he woke up?
Kid's Story: at the end, it looks like Neo and Trinity found the kid's real body. But he didn't swallow the red pill, so how did they find him? Unless they don't actually need the red pill to trace someone, i.e. the red pill is just a useless surrogate only given out of respect to have the person's consent and is otherwise totally not required?
