If it was just a typo that’s one thing, but then the author eludes to Ryu living as long as Oro does being more than 100 years old. That’s the mistake there.
“Also, there is a possibility that Ingrid can travel through time, as she mentions heading to the year 210X and seeing that Ryu has somehow become a reclusive monk, implying that after Oro passed his knowledge to Ryu, he somehow grew as old as Oro did.”
You see, because the author confused the year 201X with the year 210X he leaped into a conclusion that Ryu managed to live as long as Oro did in this scenario which is not the case. So yes, typos can be dangerous especially when you are making implications as such.
And Wikipedia is wrong lots of times. Read up on Death being in love with Thanos only in Wikipedia when any Marvel fan will tell you that Death has never been in love with Thanos, how that bit of information managed to get in Wikipedia is beyond me. I’m not even going to go into the entire KOF/Lantis’ KOF Faq/Wikipedia ordeal.
